Summary: hang in snd_pcm_drain()
Description:
MPlayer sometimes hangs during uninit in snd_pcm_drain()
Sometimes one can play up to 40 files untill it happens, so this is not
easily reproducable.
Although I could reproduce it with alsa-lib-1.0.10rc3 and kernel 2.6.15rc1
and 2.6.14.
As far as I know it does not happen with 2.6.12. I did not test 2.6.13
Here is some backtrace when pressing ctrl-c (I can redo with debugging
symbols if needed)
0xffffe410 in __kernel_vsyscall ()
(gdb) bt
#0 0xffffe410 in __kernel_vsyscall ()

#23 0x00000004 in ?? ()
#24 0x08076959 in main ()
Attaching strace will make it continue.
As far as I can tell the problematic poll is in
static unsigned int snd_timer_user_poll(struct file *file, poll_table *
wait)
in sound/core/timer.c in the kernel.
I don't know if this has any importance but tu->qused in the above
function is 2, about 2 polls before the hang. During normal playback it
always seems to be 0 or 1
It might have also something to do with the many xruns I'm getting with
some files,
but I think the xruns are more likely a MPlayer problem.
The problem does not occure when using oss emulation.
Please tell me if you need additional info or if I should add some debug
printf/printks etc.

Ok I made a test app available at http://faust3.kilu.de/testcase.tar.gz
Just run the included ao_alsa_test and it will hang in the
snd_pcm_drain()
The bug is probably there for some time already. However it was hidden by
another
bug that has been fixed in revision 1.15 of alsa-lib/src/timer/timer_hw.c
Commit message:
"Summary: Change some timer ioctls due to confliction
Change values of some timer ioctls to avoid confliction with FIO* ioctls.
Use old ioctls if the timer protocol version doesn't match."
Due to this bug SNDRV_TIMER_IOCTL_STOP never reached sound/core/timer.c
in alsa-driver.
Now that the above bug is fixed and SNDRV_TIMER_IOCTL_STOP gets called,
the poll()
will hang.
This happens with all alsa driver versions since 1.0.9rc4 (where
SNDRV_TIMER_VERSION got increased to 2.0.4)
Tell me if you need more info...
