Description Valdis Kletnieks 2008-07-03 02:18:08 EDT
Description of problem: pulseaudio-0.9.10-1.fc9.x86_64 works fine. If I upgrade to a more recent pulseaudio (current rawhide is 0.9.11-0.6.git20080626), I see error messages of the form: pcm_pulse.c:274: pulse_write: Assertion `pcm->last_size >= (size * pcm->frame_size)' failed. coming out of /usr/lib64/alsa-lib/libasound_module_pcm_pulse.so It appears plugins-pulseaudio hasn't been upgraded since March 16 - does it need a rebuild against the 0.9.11 pulseaudio libraries? Version-Release number of selected component (if applicable): alsa-plugins-pulseaudio-1.0.16-4.fc9.x86_64 How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
Comment 1 Eric Moret 2008-07-03 04:19:14 EDT
Could you please try to rebuild the following src.rpm, as I don't currently have access to a 64 bit system: ftp://ftp.zouric.com/public/alsa-plugins/alsa-plugins-1.0.17-0.1.rc2.fc9.src.rpm and let me know if this package fixes your problem.
Comment 2 Valdis Kletnieks 2008-07-03 07:04:51 EDT
Nope - obviously there's something subtle going on - I rebuilt alsa-plugins 1.0.17 from that src.rpm against the 0.9.11 version of pulseaudio-libs-devel, and the result still throws the assert. I'm looking at pcm_pulse.c:update_ptr(), and I think I know what the problem might be - pulse_write calls update_ptr, which sets last_size to whatever pa_stream_writeable_size() returns. We then check that there's enough space for 'size' frames of audio. In other words, if we ever try to write out a sample that's bigger than the immediately available buffer, we immediately blow chunks, instead of looping and writing the *available* amount out, and then trying again. Apparently, pulse 0.9.11 has different timing constraints, so where 0.9.10 was able to clear the buffers out on an almost guaranteed basis so we never overran, we now com into pulse_write() while the buffer is still partly full, we run out of space, and we die. This failure probably was *possible* under 0.9.10, just a lot harder to hit. Notice that pulse_read() has a 'while (remain_size > 0)' loop instead of an assert - I wonder if pulse_write should be doing something similar.
Comment 3 Eric Moret 2008-07-03 11:13:50 EDT
Reassigning to pulseaudio maintainer which happens to be upstream as well. This might be related to the pulseaudi glitch-free branch: http://0pointer.de/blog/projects/pulse-glitch-free.html

Comment 6 Hans de Goede 2008-07-25 06:42:47 EDT
I'm seeing this too, Lennert let me know if there is anything I can do te help fix this, any patches I can test, things you want me to try etc. I can reproduce this on rawhide (including with the 0.9.11 final release which just hit rawhide) with pretty much any audio using application. To those in the CC, if you are also seeing this, do you happen to have an nvidia chipset ? For example on my x86_64 system lspci says: 00:06.1 Audio device: nVidia Corporation MCP55 High Definition Audio I'm asking this because I've been looking at other bug reports and this might be related to having an nvidia chipset.
Comment 7 Hans de Goede 2008-07-25 06:54:46 EDT
Additional note SDL applications, which still use esd by default due to SDL_AUDIODRIVER=esd in the environment, and other esd uses, such as the gnome system sounds are very quiet and sometimes (usually on close) tend to hang.
Comment 8 Hans de Goede 2008-07-25 07:18:51 EDT
One last maybe important hint, when I start pulseaudio from a terminal I get: W: pcm_hw.c: SNDRV_PCM_IOCTL_DRAIN failed And each time I start an audio using app this message gets repeated a couple of times.

The reason why I started k3b as root is because of some permission problem on my rawhide box I was too lazy too investigate/fix.
Comment 10 Valdis Kletnieks 2008-07-25 14:49:31 EDT
Not an NVidia audio chipset here either: 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01) The actual codec: % grep Codec /proc/asound/card0/codec#0 Codec: SigmaTel STAC9200 (although I'm quite convinced the problem is at a higher level - looking at the code indicates we're getting borked up before we ever get anywhere near the actual audio hardware - see the analysis in comment #2)
Comment 11 Valdis Kletnieks 2008-07-31 17:05:26 EDT
Created attachment 313132 [details] Hack out an assert that causes issues. This is total brute-force-and-ignorance. The assert trips unexpectedly, lose the assert. I have *not* investigated what Bad Things might happen if it keeps going, but the resulting library seems to Work For Me.
Comment 12 Valdis Kletnieks 2008-07-31 17:07:31 EDT
Well, fsck it - pulseaudio 0.9.11 came out, and then libcanberra started requiring 0.9.11, with the end result that I could either fix this bug, or deal wtih the fact that everybody and their pet llama is linked against libcanberra (as I found out when even frikking "ssh-askpass" started crashing). Since I couldn't figure out what the problematic assert was doing, or why, I did the attached brute-force-and-ignorance patch. Tom Duff's First Law of Systems Programming: "Never test for an error condition you don't know how to handle anyhow". So I just #if 0'ed the one assert, and the result *seems* to work just fine, including known cases that tripped the assert.
Comment 13 Ilya Eremin 2008-08-31 10:19:29 EDT
With the latest xine updates this is still broken... Firefox crashes every time on flash with audio
Comment 14 Lennart Poettering 2008-09-09 15:59:19 EDT
This is fixed in alsa-plugins 1.0.18rc which Jaroslav promised to upload soon (and before the freeze). This bug may be closed then.
Comment 15 Matthias Clasen 2008-09-13 20:59:00 EDT
1.0.18 rc3 is in rawhide
