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.

OK, we may be on to something. Register 26 is:
#define AC97_POWER_CONTROL 0x0026
But, AFAICT bit 0x8000 should only affect the modem.
After resume try:
echo 26 800f > /proc/asound/card0/codec97#0/ac97#0-0+regs
Does it restore your sound?

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.
