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.

So you are using suspend2 to suspend?  That's completely different.

What happens if you suspend the normal way?

Disabling suspend2 does not seem to make any difference. 
Well, it does sleep using ACPI anyway, but with additional scripts (I use
it since it allowes one to kill all application that use sound before
sleep/suspend)
Anyway, here are dmesg that I get with ACPI sleep without suspend2:

the sound doesn't come up after suspend, rmmod modprobe enables it as
before.
I have also enabled debug mode when configured alsa (--with-debug=full).
This gives me some more messages when I try to sleep while playing some
audio (in xmms or xine). Those messages appear right after I start to
resume:

Note that I get no sound after resume regardless whether the sound device
is used or not - it suffices if the module snd_cs46xx is loaded.

Just an observation: I tried to figure out what has been changed since
v.1.0.10, however, I noticed that the content of
alsa-driver-1.0.****/pci/cs46xx/ is identical in v.1.0.10, v.1.0.11rc1 and
v.1.0.11rc3.
