No sound - Alsa - Realtek ALC655 rev 0 - snd_intel8x0

I've had this arch setup running for almost 8 months now, and after a kernel update in late November / early December, I lost sound output. I haven't tested sound input. Since I have a little more free time now, I took the opportunity to gather as must debug/diagnostic info as I could possibly think of. Alsa seems to detect the card, but there's still no sound. Any help would be appreciated. I can post more info if necessary, just let me know what you need.

Thanks!

* EDIT: 01/12/2009 - Added debug info from alsa-info.sh *

Re: No sound - Alsa - Realtek ALC655 rev 0 - snd_intel8x0

I had same issues when I first got onto Arch. All I can say is try OSS. If it works you are better off with it than ALSA anyway.

I'm more familiar with ALSA, and I would prefer to stick with it if I can. Can anybody help me troubleshoot this?

Re: No sound - Alsa - Realtek ALC655 rev 0 - snd_intel8x0

Hi, try change !snd_pcsp to !snd-pcsp in your rc.conf. It works for me.
My cards:
lspci | grep -i audio
00:10.2 Multimedia audio controller: nVidia Corporation MCP51 AC97 Audio Controller (rev a2)
03:06.0 Multimedia audio controller: VIA Technologies Inc. ICE1712 [Envy24] PCI Multi-Channel I/O Controller (rev 02)
Good luck.
