problem posted in the gentoo forums:
I just bought a compaq presario r3128rs laptop...and I can't get my sound working at all. lspci says that it's a ATI IXP AC97 or something. I'm using kernel 2.6.8, and I've even tried compiling every single alsa pci driver into the kernel, but I'm still getting the same error and no sound.
Is this a bug in the kernel?
