Description Gianluca Renzi 2004-10-03 17:24:01 UTC
Description of problem:
After reinstalling FEDORA CORE 2 over a pre-existing RH9 up-to-date
and recompiled the sources (kernel 2.6.5-1.358) because of the lack of
IEEE1394 support from CD installation I got this problem using any
kind of sound software:

With xmms and using mpg321 (recompiled both from the sources) I got
randomly this error:
pcm.c:5896: snd_pcm_mmap_commit: Assertion `frames <=
snd_pcm_mmap_avail(pcm)' failed.

Version-Release number of selected component (if applicable):
xmms 1.2.10 and mpg321 version 0.2.10. 

How reproducible:
Launch xmms and/or mpg321 with an mp3 file and wait 'til it crashes (7
times over 10) (with or without log!!)

Steps to Reproduce:
1. Boot Machine
2. launch xmms and/or mpg321 with mp3 file (doesn't care about bitrate)
3. Wait the error!
Actual results:
It crash and stop working. Afterward it seems to be difficult to
launch xmms again due to a segfault on startup.

Expected results:
Work as before in rh6.1 to rh9.0. It has to play music!

Looks like an ALSA bug.  But it would be helpful if you tried from a
fresh installation - particularly with a stock kernel.

Comment 2 Bill Nottingham 2004-10-05 04:00:57 UTC
What sound driver?

What about FC3? Does the bug survive?

Comment 5 Gianluca Renzi 2005-01-12 19:30:44 UTC
I don't have FC3 installed, nor I am going to install it.
Anyway I upgraded the kernel to 2.6.10-1.8_FC2smp via yum/up2date.
Now I am playing a mp3 file via network using xmms feature to load
from a website (www.live365.com). As soon the bug reappear I will
inform you.

Best regards,

Comment 6 Gianluca Renzi 2005-01-14 07:59:59 UTC
Here is again!!
After a few minutes of working (playing with volume control even in
xmms, or in the system volume control) it crashes with the following:

Jan 14 08:47:17 devil modprobe: FATAL: Error running install command
for sound_slot_1
Jan 14 08:51:31 devil last message repeated 2 times
Jan 14 08:54:01 devil last message repeated 2 times
Jan 14 08:54:01 devil modprobe: FATAL: Error running install command
for sound_slot_1

And from the terminal where I launched xmms from:
[user@devil user]$ xmms
xmms: pcm.c:5896: snd_pcm_mmap_commit: Assertion `frames <=
snd_pcm_mmap_avail(pcm)' failed.

This machine is an IBM Intellistation MPRO with dual PIII-Katmai
CPU@550Mhz 512MB RAM - Kernel smp. 2.6.10-1.8-FC2

I hope this can help.


Comment 7 Matthew Miller 2005-04-26 15:19:02 UTC
Fedora Core 2 is now maintained by the Fedora Legacy project for
security updates only. If this problem is a security issue, please
reopen and reassign to the Fedora Legacy product. If it is not a
security issue and hasn't been resolved in the current FC3 updates or
in the FC4 test release, reopen and change the version to match.

Comment 8 Martin Stransky 2005-05-09 10:50:15 UTC
Do you have any ~/.asoundrc or /etc/asound.conf file?

Comment 9 Gianluca Renzi 2005-05-09 17:57:41 UTC
No, I have only /etc/asound.state file only.
I found if I switch to OSS no problem occurs.

Comment 10 Martin Stransky 2005-05-10 09:55:07 UTC
It has been reported to upstream and bug track for it is here:


I'm closing it as UPSTREAM.
