Created attachment 316691 [details] Analysis of a similar problem I have a similar problem on my system, which also occurs very frequently when I use KDE 4 desktop effects, e.g. move or resize a window, switch between desktops, or even quickly scroll text in kwrite. These actions also cause noticeable interruptions in the sound flow, even when pulseaudio stays alive. I debugged it a bit, and it seems that it is mainly a driver or hardware bug. However, I think that pulseaudio should check values that it gets from ALSA, instead of diving into a semi-infinite loop. Hardware driver: HDA Intel.
Created attachment 316695 [details] Workaround patch for alsa-lib With this patch pulseaudio on my system simply prints error messages instead of crashing: ALSA lib pcm_local.h:423:(snd_pcm_mmap_playback_avail) Playback backtrack detected: -3104 ALSA lib pcm_local.h:423:(snd_pcm_mmap_playback_avail) Playback backtrack detected: -1976 ALSA lib pcm_local.h:423:(snd_pcm_mmap_playback_avail) Playback backtrack detected: -928 ALSA lib pcm_local.h:423:(snd_pcm_mmap_playback_avail) Playback backtrack detected: -664 ALSA lib pcm_local.h:423:(snd_pcm_mmap_playback_avail) Playback backtrack detected: -1160 ALSA lib pcm_local.h:423:(snd_pcm_mmap_playback_avail) Playback backtrack detected: -72 Disclaimer: this patch does not fix the real problem.
I suspect it can be connected with the latest kernel update to version 2.6.26.3-29.fc9.x86_64. With the earlier kernel version (2.6.25.14-108.fc9.x86_64) pulseaudio was quite stable.
This is very interesting, and I actually believe quite a few bug reports are related to this.
I brought this up the alsa ML: http://mailman.alsa-project.org/pipermail/alsa-devel/2008-September/010841.html http://mailman.alsa-project.org/pipermail/alsa-devel/2008-September/010845.html http://mailman.alsa-project.org/pipermail/alsa-devel/2008-September/010846.html Could you please try again with 2.6.27 from rawhide as suggested?
(In reply to comment #6) > Could you please try again with 2.6.27 from rawhide as suggested? Will it work with a Fedora 9 installation? Some people say it won't, and I don't want to break my system. With the current kernel I can make this problem manifest simply by rapidly minimizing and unminimizing Firefox several times. When the glitch happens, a tiny fragment of sound is repeated several times, and, appparently if pulseaudio tries to update at the right moment, a warning message from my patch. Btw, perhaps it would be useful for me or somebody else to upload a complete patched alsa-lib rpm, so that the original submitter of the bug can try it and confirm/disprove that the cause of his problems is identical to mine?
You'd have to do a full update to rawhide i fear.
Same problem here. Confirmed with Alexander Gavrilov alsa-lib patch.
You can also just test with the module from 2.6.27. 1) Backup /lib/modules/`uname -r`/kernel/sound/pci/hda/snd-hda-intel.ko 2) Download 2.6.27 sources from kernel.org 3) cd sound/hda 4) make -C /lib/modules/`uname -r`/build modules 5) copy the resulting snd-hda-intel.ko to /lib/modules/`uname -r`/kernel/sound/pci/hda/snd-hda-intel.ko 6) run /sbin/depmod -a 7) reboot 8) try to reproduce the bug.
I've been using a snd_hda_intel.ko (built from 2.6.27-0.392.rc8.git7.fc10 source) with 2.6.26 kernel on fc9 for 2 days. It has resolved the issue. BTW, steps above .... 2) cd sound/pci/hda 4) make -C /lib/modules/`uname -r`/build M=$PWD modules
The fix from comments 10/11 appear to have resolved the problem for me too.
Should we re-assign this bug to the kernel? The latest 2.6.26 builds in koji (2.6.26.6-74) do not contain a fix for the issue. Perhaps if it is re-assigned to kernel the maintainers can backport the hda-intel from 2.6.27 to 2.6.26 for fc9? (Especially, if a 2.6.27 for fc9 is not going to be released in the near future.)
Yes, should be reassigned IMO.

We can't backport the entire driver. Can the ALSA developers identify the patches that fix this problem?
I'm not an alsa developer! And I need to verify this, but someone with more of a clue might be able to take this as a hint and pick up on it. I believe the patch that caused the 'breakage' in 2.6.26 series kernels ..... http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.26.y.git;a=commitdiff;h=9ad593f6d326e7a4664e3856520f6c042f82a37f And I think the patch (from 2.6.27) that will resolve it .... http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.27.y.git;a=commitdiff;h=675f25d4d3ff6501cbce608bcc2333a56ec4c105 But I'm guessing a bit here as I just created a diff to the entire sound/pci/hda of 2.6.27 to fix this, which includes several other patches relating to the new bdl code. I'll test tomorrow with individual patches in no-one else jumps in.
After more testing, I can now reproduce this with 2.6.25, 2.6.26, 2.6.26 plus hda-intel kmod from 2.6.27 and 2.6.26 plus alsa-driver-1.0.18rc3. It is load related. Later alsa code definitely helps. ie. load average needs to be higher for it to occur. Stock fc9 2.6.26 kernels need very little load for the problem to manifest. 2.6.25 kernel or 2.6.26 plus alsa code from 2.6.27, load average > 10 before problem occurs.

there is some confusion in bug connection to different platforms My system is F10 x386. Suffered from it on F9 on my desktop, not on on my laptop. Now both systems are suffering
Changing component to "rawhide". I'm having same problem here, F-10 fully updated, snd-hba-intel driver. Bug is 100% reproducible, although may take up to an hour of playing to trigger it. Kernel is kernel-2.6.27.3-27.rc1.fc10.i686 > aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: AD198x Analog [AD198x Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 1: AD198x Digital [AD198x Digital] Subdevices: 1/1 Subdevice #0: subdevice #0
I also encounter this problem on Rawhide but it is far less serious than with F9 and only happens after some time.
I have never seen this problem with F9 but it is reproducible with F10/rawhide on snd-via82xxx. In my experience it is triggered when something else is using CPU cycles while pulseaudio is active.
i say in Comment 29 (fedora 9 + kernel 2.6.27.2) pulse audio work fine, but that is not true. i got error now, really rare staff.
I am trying to figure out how this is a kernel bug. If you erase pulseaudio does everything work?
Chuck if someone thinks that is kernel related (me included), it is connected to the fact that some kernels give better results in particular with reference to spikes (but not of dying of sound application)
Is it a kernel bug? I think so. On F9 with kernel 2.6.26.5-45.fc9.x86_64 I see this happening with pulseaudio but if I have rhythmbox outputting directly to alsa then I don't seem to have any problems. Patching in snd-hda-intel from 2.6.27.1 seems (based on limited testing so far) to have stopped pulseaudio dieing.
As mentioned by Lennart, it's a kernel bug (i.e. alsa driver). Although PA has a knack for crashing or quitting as soon as an alsa driver misbehaves slightly, especially when it quits with this message: > Hard CPU time limit exhausted, terminating forcibly.
*** Bug 467891 has been marked as a duplicate of this bug. ***
Yes, I am pretty sure this is a kernel bug, but I am not entirely sure yet. Today for the first time I have been able to reproduce this issue here locally. Unfortunately on Rawhide we have no even remotely working debugging tool. gdb is a mess (bug 468129), frsyk doesn't work either. Neither does oprofile (467651). For the first time I managed to reproduce this -- after days of trying. I finally have PA spinning in this loop. And I have no way to find out what is going on.
OK, so I am one step further. First, this issue has multiple different causes. I nailed at least one of them, which was specific to 32bit machines which is the reason I was unable to reproduce this on my 64bit machine. The fix is trivial: http://git.0pointer.de/?p=pulseaudio.git;a=commitdiff;h=b712e7b13dd6aed3e56eaee423ff071d6f0ce2c2 Brrr, I lost too much time on this one. This patch is included in 0.9.13-4. So, everyone, please give it a try. It's in koji right now. This should hopefully fix the issue for the majority of people. Still there seem to be some driver issues left. I know for sure that the Creative ALSA drivers are borked. 0.9.13-4 includes some diagnostic code that will verify the results of a couple of ALSA calls and log a warning if they are inconsistent or have values that are suspicously high. So, even if you have a Creative card, give this a try and watch your logs. It will hopefully give us a hint what is wrong so we can inform the ALSA people about this.
Lennart, Can you backport the bugfix (if applicable) and logging code to 0.9.10 on fc9, please?
Lennart, I'm somewhat confused - does the Creative labs fix apply to x86_64 as well? When can we expect to see 0.9.13-4 in koji/updates-testing on F9? - Gilboa
Lennart I have been playing sound (radio streaming) longer than before on my desktop with snd-hda_intel and I would say that you have found the solution. I will report later, same laptop will come (and play) to my office in a few moments... Tnx a lot

Only difference is hardware My laptop profie is here: http://www.smolts.org/show?uuid=pub_2dabf29b-bd26-4825-b7ed-ac1db85fec24
and finally Rhythmbox crashed after two hours of good music :-) on my laptop

Antonio: none of your logs shows any crash. What kind of crash is happening for you? Also, the two SMOLT links point to the same profile.
(In reply to comment #42) > Lennart, > > Can you backport the bugfix (if applicable) and logging code to 0.9.10 on fc9, > please? Uh, this doesn't really apply to 0.9.10 for now. Let's first get the 0.9.13 issues straightened out. For 0.9.10 I am pretty sure the remaining issues are driver issues, btw.
antonio -- are you sure you are using 0.9.13-4, btw? i don't think -4 is already in rawhide.
(In reply to comment #43) > Lennart, > > I'm somewhat confused - does the Creative labs fix apply to x86_64 as well? There is no fix for Creative labs cards. Just some diagnostic code that will hopefully show in a proper message what is going wrong with the driver. > When can we expect to see 0.9.13-4 in koji/updates-testing on F9? No. PA > 0.9.10 uses glitch-free for playback which is the part responsible for triggering all the bugs since this uses ALSA functionality that nobody used before and that is clearly broken. I won't backport that to F9.

But when you look in the logs there are some rewinds, and at the same time I see buffer of Rhythmbox empty and refuelled...(i.e. a small interruption) http://www.smolts.org/show?uuid=pub_2dabf29b-bd26-4825-b7ed-ac1db85fec24 is the profile of the desktop that is untill now is more affected than the laptop. At the moment I am playing a radio stream on the desktop with: kernel 2.6.27.3-39.fc10.i686 pulseaudio-0.9.13-4.fc10.i386 (same software is on the laptop) But while with same software this morning I experienced small interruptions and rewinds now it seems o.k. I need more tests. I will come back when something new will happen
i made a test... I installed latest kernel in koij 2.6.27.3-44.fc10.i686 and small interruptions are back again. Is pulseaudio or kernel or both causing problems???

I suspect that Bug 468332 is a duplicate. If someone can confirm that my concerns are those addressed in this bug, I will close. I should add that I have intel sound on the motherboard, but it is disabled in the bios. I use a creative soundblaster 1024 live value (ct4830 with midi) pci card. I am using f10 (rawhide) on i386 architecture.
I think that is a duplicate, as 466027 that I deleted. Final word to Lennart :-)
*** Bug 468332 has been marked as a duplicate of this bug. ***
Is this only intel8x0 and Creative cards that create those drop-outs even with 0.9.13-4? Or is anyone else affected, too? If you add yourself to the group pulse-rt, does that change anything?
no..it doesn't change anything. I am fighting with this problem since F9, and basically in the last month of F10 as for a short period sound was good And I am not alone on the boat. What changed??? this is the real question.... for sure, now it is not easy to check back all mods. Any help I can give, I am here.... I still think that something is broken in kernel.(maybe because when running F9 I solved the problem installing one kernel from F10).

I am here as filer(?) of duplicate bug 466530 and has 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02) kernel-2.6.27.3-39.fc10.i686 snd_hda_intel pulseaudio-0.9.13-4.fc10.i386 running as pulse-rt group member My experience is that it works quite well for me now, and I haven't noticed any problems recently. That proves nothing, perhaps except that it wasn't a duplicate anyway, but right now I'm happy.

What gives problem is the ICH5 family, also in the past....
antonio: so if i understood properly it's specific to intel8x0 (and Creative) cards, is that correct.
I have been in group pulse-rt all along and the problems occurred. I have applied the update, regrettably no time yet this afternoon to listen to music, play videos, will experiment this evening.
I can also confirm that I never ever had this problem until just a day or three ago (but I wasn't listening to a lot of music or watching videos for a bit, recently). Until yesterday, that is.
(In reply to comment #70) > antonio: so if i understood properly it's specific to intel8x0 (and Creative) > cards, is that correct. I think so but I do not have other cards :-) . But if you dig in bugzilla, I remember that there was a bunch of bugs stating that it was a problem of timing....I think that reporter was Antonio Olivares. For sure it is a big problem...I don't like listening to sobbing music :-) And it must be solved before F10 release

I now had several reports of intel8x0 cards still not working with 0.9.13-4. Anyone having issues on other hardware? Creative cards anyone?
Now pulseaudio doesn't seem to die but I am experiencing sound glitches. It was better when pulseaudio died but until then I could listen to music :-)

Ok, I did watch some vids. After about 5-10 minutes, the problem recurred: the sound began sputtering and ultimately cut out. Restarting the application or switching to another application to watch the video did not help. There was no sound. I didn't try killing and restarting PA, however. I am using: pulseaudio-0.9.13-4.fc10.i386 kernel-2.6.27.3-39.fc10.i686 SoundBlaster/i386 Someone earlier mentioned that they had this already in F9. I never saw it until yesterday or day before.
Petrus: SoundBlaster? An original SoundBlaster? Sorry, I don't believe you. What driver do you use? i.e. snd-emuxxxx or something? Please provide an output of "pulseaudio -vvvv" when that happens (start in a terminal, possibly run pulseaudio -k before).
"SoundBlaster? An original SoundBlaster? Sorry, I don't believe you." How do you quote here, so it shows with > purplequotedtext ? On the board, it says Creative SoundBlaster Live! Value (CT4830), but KDE Info Centre reports (CT4832). It uses the emu10k1 kernel module. You mean I should run "pulseaudio -k ; pulseaudio -vvvv" after the error occurs, or "pulseaudio -k", wait for the error, and then "pulseaudio -vvvv"? You will have the results in a few hours (I have to go for a bit).

So it's a SoundBlaster Live!, not an original 1989 SoundBlaster... > You mean I should run "pulseaudio -k ; pulseaudio -vvvv" after the error > occurs, or "pulseaudio -k", wait for the error, and then "pulseaudio -vvvv"? No. pulseaudio -k stops a running PA. pulseaudio -vvvv starts a new one with debugging output enabled and without detaching. i.e. run that in a terminal and you'll get the PA output right into that terminal. Then, do your testing and you can see the debug output it causes directly in the terminal. Then, paste that data from the terminal so that I can see what is going on.
Created attachment 321485 [details] output of pulseaudio -vvv I ran music videos for a long time, but the glitch did not recur like yesterday. Yesterday, I had been using firefor and viewed a lot of the videos online via the Adobe flash-plugin. I did not want to contaminate this log with Adobe flash, so I played both saved flv and mpg files. I noticed a lot f crackling and some occasional stuttering, but the music never cut out, like it had previously. There were literally 10s of thousands of the E: module_alsa_sink.c lines. I cut out sections that show some other stuff, too. Hopefully, I didn't lose anything relevant. Toward the end, I grew impatient and grabbed the program by the frame with the mouse and rapidly draged it back and forth across the screen. The music playback went wild with echoes, strutters and reverberation. It composed itself nicely when I brought the program window to rest on the screen.At the very end, I had to type ctrl-c to break out of the command. This is that output.
So, after running the test above, I did not restart the pulseaudio daemon, but continued watching music videos on youtube. I experienced absolutely no problems with it: no sould problems, decaying into pops and squeals and ultimeately silence; no strange video dropouts with the sound continuing and the video then catching up in fast-forward. All seems to run well. This suggests that pulseaudio is the cause of these problems, as they disappear when pulseaudio is disabled.
I ran into this bug on my Mandriva Cooker system with pulseaudio-0.9.13. The sound is jerky after less than an hour of playing and there are artifacts when starting to play a new file.

I cut out sections that show some other stuff, too. Ah, this is very interesting. The "multi" plugin for ALSA apparently sends us an POLLOUT and the immediately following snd_pcm_avail_update() returns 0. That is clearly a bug in this ALSA plugin. I will bring this up on the ALSA ML. Could you please repeat your testing, however with using only 2ch? I.e. reset your default.pa to use only two channels? This will move the "multi" plugin out of the pipeline. (In reply to comment #87) > This suggests that pulseaudio is the cause of these problems, as they disappear > when pulseaudio is disabled. It's not that easy. PA uses a lot of functionality of the ALSA drivers noone else has apparently used before or relies much more on the correctness of the data (such as timing) ALSA returns. That's why PA triggered and stiull triggers many bugs in the ALSA drivers that weren't apparent before.

I want this to work, once it is all fixed.
Just a little update: I upgraded to the new kernel-2.6.27.3-44.fc10.i686. I did not run pulseaudio -vvv and I haven't edited my configuration file to use only 2 speakers. I was just happily enjoying music online. What I noticed is that I had NO problems with Adobe flash-plugin whatsoever, not with sound nor with video (I suspected the two problems were related, as the one would continue, then the other would spool in fast-forward to catch up after a pause of a few minutes, etc). Then, I played some saved flv and mpg files using kaffeine and vlc. I grabbed the program frame and dragged it rapidly to and fro on the screen, and the video and audio kept on playing perfectly. I might have heard a pop or two, but I cannot rule out some imperfections in the media.
Created attachment 321529 [details] output of pulseaudio -vvvv Ok. I did it. I commented out the 4 speakers in daemon.conf, killed the daemon and started it with -vvvv. Here is the output. I played videos, both mpg and flv, with vlc, with kplayer and with kaffeine, in order to get some output from 3 playback systems (I did not use Adobe flash-plugin, only playing files from my computer). Anyway, I noticed that there was a lot of clicking and popping, really A LOT. I moved the window around on the screen, but it never hung up or reverberated like it had yesterday, although there were some dropouts. I noticed that when I opened and repeatedly maximized/minimized firefox, there were some 'module-alsa-sink.c underruns'. Also, I spooled ahead a few times, but I noticed that a lot of these 'rewinds' occurred, even when I hadn't been spooling ahead, but must have opened or closed a window (although I didn't notice that the music had stopped or that the picture had jumped - they must have been minute 'rewinds', but they occurred quite a lot). I hope there is something useful here.
Help! As a result of the editing of daemon.conf that I did above: I had only made 2 changes: I noticed that there was /etc/pulse/daemon.conf.rpmnew, so I compared it with (the old) daemon.conf. There were only 2 differences: the new one had the line ; shm-size-bytes = 0 # setting this 0 will use the system-default, usually 64 MiB and the old one didn't; and the old one had default-sample-channels = 4 enabled and changed to 4 from 2 to allow me to use both sets of speakers (I know it all worked about 2 weeks ago, as I had used the other speakers then, when blasting the house with music - both sets of speakers worked). I thought I might as well use the new version of the file and simply enable the 4 speakers in it, after doing my testing and reporting above. Then, I turned off the computer for a while, and later, rebooted, only to find that now the sound comes from the 'other' set of speakers. I have checked kmix and I have the volume enabled for both sets. What is curious is that when I open the volume control in the pulseaudio applet, the main speakers beep, but ALL other sound comes from the secondary speakers. Formerly, I had all sounds coming from both sets of speakers, so I could selectively turn the one set on and the other off, depending on which room should have music. Also, although I have 2 sets of speakers, shown as front and surround in kmix, there is only one front left/right slider in the pulseaudio volume control applet and none for surround right/left, i.e., the other speakers. Wasn't one of the selling features of pulseaudio, that one could control volume output separately for different hard- and software at the same time, as well as directing different audio streams to different speakers?
I had done a restorecon -v './daemon.conf', just in case, but maybe pulseaudio didn't reread the file, if that was even the problem (selinux showed no output, as it normally would when changing a file's context). Then I rebooted a second time, and now I am all striaght again.
I tried to reproduce the bug on: [sk@digger ~]$ uname -a Linux digger 2.6.27.3-44.fc10.i686 #1 SMP Fri Oct 24 00:40:32 EDT 2008 i686 i686 i386 GNU/Linux [sk@digger ~]$ rpm -q pulseaudio pulseaudio-0.9.13-4.fc10.i386 [sk@digger ~]$ lspci | grep Audio 00:1e.2 Multimedia audio controller: Intel Corporation 82801G (ICH7 Family) AC'97 Audio Controller (rev 01) The bug is triggered perfectly for me on heavy sound load - I played flac music with rhythmbox and ran foobillard on the background. The sound was glitching all the time on foobillard balls collision (it plays a small sound then). I failed to get the whole 'pulseaudio -vvv' output but this is a typical piece of it: I: module-alsa-sink.c: Underrun! D: module-alsa-sink.c: Wakeup from ALSA!

Created attachment 321551 [details] Pulseaudio daemon messages after updating to 0.9.13-4 I updated pulseaudio on Friday and played several hours of music since then (mplayer - MP3 radio stream from Internet, amarok 1.4 - Ogg Vorbis encoded music collection). I have not been able to reproduce the pulseaudio looping problem again. Good work Lennart! For reference: $ uname -a Linux baraddur 2.6.27.3-44.fc10.i686 #1 SMP Fri Oct 24 00:40:32 EDT 2008 i686 athlon i386 GNU/Linux $ rpm -q pulseaudio pulseaudio-0.9.13-4.fc10.i386 $ lspci | fgrep audio 00:11.5 Multimedia audio controller: VIA Technologies, Inc.

The only disturbances I got were - very short interruptions at the beginning of a new audio stream until pulseaudio has found the correct watermark for the system. It might be a little bit too optimistic about the speed of this slow laptop. Is there maybe a way to set the initial watermark value? - twice under high load there was a short replay. Those two occasions are visible in the attached log But I guess by either setting a high initial watermark value or allowing high priority scheduling I would have absolute glitch-free pulseaudio playback on this machine.
2.6.27.4-51.fc10.i686 kernel seems great.....I am testing with sound in Rhythmbox playing radio stream and I am not experiencing any problem so far. I feel that quality of sound is improved, maybe only suggestion???? :-)
Unfortunately this is only a suggestion. Better but glitches still present when two or more applications play sounds.
(In reply to comment #99) > Unfortunately this is only a suggestion. Better but glitches still present when > two or more applications play sounds. I played at same time Rhythmbox and Xmms and I didn't get any glitch..Music seemed o.k. I noticed that Xmms volume controls PCM general slide, so if you reduce volume in XMMS all applications's sound goes lower. Is it normal???
Quick summary of the status quo: I think that 0.9.13-4 is fine for f10 so far. The remaining issues are specific to intel8x0 (and some Creative cards) apparently. Unfortunately I have no access to such a card and hence cannot figure out what's misbehaving on them. Unless someone supplies me with the necessary hardware (anyone got a spare intel8x0 or emu10k1 machine/card and lives near berlin/germany?) I fear this bug will stay unfixed for F10.
with today's kernel and Rhythmbox I am again experiencing buffer underruns in Rhythmbox, I am back to the poor situation of two weeks ago. And I am running intel8x0: I suppose that some cents for Lennart's hardware should be found in some coming event!!! kernel 2.6.27.4-68.fc10.i686 rhythmbox-0.11.6-15.6005.fc10.i386 and now also Vlc plays bad... If situation continues, what shall I do?? install a different distribution after so many years???? :-(
Created attachment 322163 [details] Log of pulseaudio -vvv using VLC I am experiencing small interruptions also in VLC
Created attachment 322164 [details] Log with Rhytmbox Similar log with Rhythmbox with latest 2.6.27.4-69.fc10.i686 kernel. And after a while streaming lock and plays same small part of streaming!!!
upgraded pulseaudio to pulseaudio-0.9.13-6.fc10.i386 this evening and troubles seem gone :-) I will come back after a longer test ...
no..troubles have not gone, still suffering of small breaks and rewinds.Yesterday, everything seemed o.k, booted this evening and I am experiencing same problem immediately.
I had the same issues as the commenter #97, and now I don't see PA being killed anymore. So to me the situation is definitely better on my system.
funny as my comment #108 was while running kernel 2.6.27.4-69.fc10 that I had grabbed from koij, I reverted to .68 and everything seems o.k. Now I don't know if solution was due to rebooting or to switching to another kernel.
Hi, it looks like the attention is on f10 (which I understand!) Any plan or looking at f9 too? As far as I understand, I have the problems described at the top of the thread.

I'm seeing an issue that *might* be this one. I'm running the latest RT kernel (2.6.29-rc6-rt3) on top of an up to date F10. Periodically my pulseaudio dies and must be restarted by hand. If I run pulseaudio in the foreground with $ pulseaudio -vvv --daemonize=false I get the normal spew of debugging output and eventually I see 'Killed.' and pulseaudio stops. The message implies that someone sent pulseaudio a SIGKILL, but I have no idea who would be doing that. I do notice that it seems to correspond with an activity spike on my cpu usage graphs. Any ideas?
I think this might be related. A week or so ago I started hearing sound stop working after about 5 seconds when playing something with xmms. I ran in the foreground and got the following error output: E: alsa-util.c: snd_pcm_delay() returned a value that is exceptionally large: 457348 bytes (2592 ms). E: alsa-util.c: Most likely this is a bug in the ALSA driver 'snd_intel8x0'. Please report this issue to the ALSA developers. E: rtpoll.c: Assertion 'usec <= ((pa_usec_t) 1000000ULL)*60ULL*60ULL' failed at pulsecore/rtpoll.c:548, function pa_rtpoll_set_timer_relative(). Aborting. Aborted
And another one that is a bit different: I: alsa-sink.c: Underrun! N: alsa-sink.c: Increasing wakeup watermark to 30.00 ms E: memblock.c: Assertion 'length' failed at pulsecore/memblock.c:356, function pa_memblock_new_fixed(). Aborting. Aborted
Bruno, the intel8x0 issue has been reported already as bug 472339. Could you please get me a stack trace for the pa_memblock_new_fixed() issue.
I probably won't get a chance to do it tonight, but I'll try to get it to happen again and get the stack trace info. (I don't know how to do that off hand, but I'll look for options to run the deamon with to see if one of them does it.)
I retested it after updating to yesterday's rawhide (which had pulseaudio and may have had glibc changes). I still get the memblock failure some of the time. I haven't been able to get a stack trace. When pulseaudio exits it doesn't leave a core file. (I raised the coredumpsize limit.) I can't get it to run reasonably under gdb in order to reproduce the problem. I didn't see any obvious option for generating a stack trace when an assertion failure occurs. Can you suggest how I might get a stack trace for you?
Please follow the hints in this wiki page: http://pulseaudio.org/wiki/Community#BugsPatchesTranslations
I am not seeing any crashes now (after updating to kernel-PAE-2.6.29.1-70.fc11.i686), so either my other error was related to the one I was seeing most of the time or both issues got fixed at the same time.
I think most of these have now been fixed in the kernel. (At least regarding HDA and intel8x0). There is still a bug open regarding the ens1371 driver, though. I will now close this. Remanaing issues should be dealt with in seperate bug reports for the various drivers.
Although this bug is supposedly fixed, I am not so sure. I have had chronic problems with identical-sounding symptoms with an Intel ICH5 system and ALSA. Pre-FC11, I got around the problem by using the OSS driver, which worked fine with this sound processor. In FC11, OSS has been killed off, so I had to revert to the ALSA driver. It still does not work correctly with ICH5. Here is my info Linux l2.fu-lab.com 2.6.29.6-213.fc11.i586 #1 SMP Tue Jul 7 20:45:17 EDT 2009 i686 i686 i386 GNU/Linux alsa-lib-1.0.20-1.fc11.i586 pulseaudio-libs-0.9.15-14.fc11.i586 alsa-plugins-pulseaudio-1.0.20-2.fc11.i586 Whether I use straight ALSA or ALSA and PulseAudio, the symptoms are the same. Playing a video with Xine is very doubtful. Typically, a movie will play for 10 to 30 minutes, the sound will then abruptly cut out, sometimes with a brief crackle. It is then dead. There are no errors reported in the system log or to the Xine console. To get sound working again, I have to stop and restart Xine. I have xine-lib-1.1.16.3-2.fc11.i586 but the symptoms have been the same with several versions of xine-lib over the past several years. If I disable the ICH5 processor and use an Audigy 2 card, sound is fine. Go back to the ICH5, and the symptoms reappear. I don't understand the Linux sound architecture. Where, exactly, is the ICH5 driver code, and why did OSS work fine with it but not ALSA? Thanks! Jim
