Subject: audacious: Hangs after a random amount of time playing music

Date: Sat, 23 Oct 2010 16:26:52 +0100

Package: audacious
Version: 2.3-2
Severity: important

Hi,

After upgrading from lenny to squeeze I've found that audacious
hangs anywhere between 10 seconds and 5 minutes after I start playing
a playlist.

When hung strace reports a tight loop of:

sched_yield()                           = 0

I haven't been able to find any common factors which would help explain
the hang, sorry. If you have any more suggestions for things to try to
debug, let me know.

Cheers,
Dominic.

Hi Dominic, thanks for your report.

Can you tell us:
- What sort of file (MP3, AAC, Vorbis, etc.) you are trying to play, and
on what medium (hard disk, CD, network)?
- What type of audio output you are using (ALSA, PulseAudio, OSS, etc.)?

Then, can you run Audacious from within GDB, stop the process when it is
hung, and take a backtrace?

Sure. From 2.3-2 with -dbg packages installed:

#0  0xb7fe2424 in __kernel_vsyscall ()
#1  0xb7735876 in nanosleep () from /lib/i686/cmov/libpthread.so.0

#4  0xb5dbae15 in snd_pcm_status () from /usr/lib/libasound.so.2
#5  0xb5dce40b in ?? () from /usr/lib/libasound.so.2
#6  0xb5dbae15 in snd_pcm_status () from /usr/lib/libasound.so.2
#7  0xb58c8003 in real_output_time () at alsa.c:127
#8  0xb58c8235 in alsa_output_time () at alsa.c:387

#16 0x08059879 in main (argc=1, argv=0xbffff504) at main.c:554

Note that running under gdb seems to reliably cause a crash after
less than a second of playback, whereas the time until crash is
more variable without.

Also, sounds appears generally well-functioning on this system; it's
not a crash that appears with other programs.

Dominic.

reassign 601120 libasound2
retitle 601120 libasound2: snd_pcm_status() hangs
thanks

snd_pcm_status should be an instantaneous call.  Reassign to ALSA package.

As we are still waiting the release of Jessie:

We have a big improvement in libasound and alsa-utils. The drivers
from the actual kernels should be tested as well, but anyway:

Ist this bug still valid for you?
