I have the same problem here.
I had Warty with last upgrades and sound worked. Burned final Hoary Install CD
on April 8, apt-cdrom added it, dist-upgraded it, rebooted with the new 2.6.10
kernel and sound stopped working. It doesn't show any errors, just can't hear a
sound. Oh... mplayer hangs.
If I reboot and select the old wary 2.6.8 kernel, sound WORKS again. So I think
it's a kernel problem and not alsa's fault. But I'm no expert.

Mother: ASRock K7S41GX (http://www.asrock.com/product/product_k7s41gx.htm).

diego at antu:~ $ cat /proc/asound/cards
0 [SI7012         ]: ICH - SiS SI7012
                     SiS SI7012 at 0xdc00, irq 177

These are the differences between the loaded modules on both kernels.

PS: I tried booting Hoary's LiveCD from Ubuntu and Kubuntu and non of them
worked either.
