Summary:                    sound is locked up after suspend/resume (APM)
Description: 
Until recently I was running oss driver cs46xx without a problem. I could
suspend in the middle of playback and xmms would keep playing after resume
as if nothing happend at all.
After switching to the 2.6 kernel, currently running 2.6.5, I also
switched to ALSA beeing the new sound architecture of choice.
Unforunately now when I suspend and resume my notebook sound stops working
at all. Sometimes unloading all ALSA modules helps, sometimes even that is
not possible anymore.

no, doesn't help.
now 
cat /proc/asound/card0/codec97#0/ac97#0-0+regs 
the same as before sleep, but there is no sound.
However I there is a message appears in dmesg:

ALSA
/usr/src/alsa/1.0.11rc3/alsa-driver-1.0.11rc3/acore/../alsa-kernel/core/pcm_lib.c:2231:
playback write error (DMA or IRQ trouble?)

Not sure at which moment exactly, but after suspend.
I'll try to repeat this and report more exatcly.

yes, the message appears after resume, when I try to play sound in an
alsa-native (for example in gnomemeeting), but not in oss-based
application (like xmms). I do not get sound in any of them.
