I have a similar problem here (ICH3M, CS4299, snd-intel8x0). In my case,
using OSS emulation in userspace and ALSA modules in kernel works fine, so
it must be a locking problem of some kind, anyway probably something
trivial to fix.
A similar problem occurs under 2.4, FYI.

Laptops and 2.6.0 - momentum? (was Re: 2.6.0 release + ALSA + suspend = not work)

[pZa1x]

Well, I'm volunteering time to do testing on my notebook for 2.6.0. I 
wonder if there is anyway to generate some momentum for it? If the aim 
is enterprise, doesn't enterprise use thousands of notebooks? I got mine 
refurbished from some large business. There are many organizations that 
collect thousands of old notebooks used by businesses, refurbish them 
and re-sell them. It's a great way of acquiring a durable, light 
business-class notebook at bargain prices.

This is a great target for Linux especially as it runs fine (even with 
the infamous Gnome) on my 700Mhz T20 Thinkpad. ie. a multi-gigahertz 
system seems a complete waste of money and a risk re weight and build 
quality.

I couldn't code a hello world to save my life but I can test patches and 
collect data. Currently, I am running 2.4.22 on my notebook because on 
2.6.0:

(a) suspend kills ALSA and ALSA mut be restarted
(b) suspend fails to function if yenta_socket (PCMCIA services) is running

[venom]

same problem with alsa on CS4236B ISA card, and sound is horrible.
no problems with OSS.

alsa work fine on Maestro pci and old good SB16 ISA.

So, probably depends on the specific driver.

2.6.0 release + ALSA + suspend = not work

[pZa1x]

ALSA stops producing sound after any time I suspend my Thinkpad T20 
notebook. I am using 2.6.0 release and the snd-cs46xx driver.

I have to log out of Gnome and remove the sound card module and re 
modprobe it then restart Gnome to get sound back.

No problems with 2.4.20 with OSS drivers.
