I didn't see the original post since I'm a new subscriber but I figured I'd
add my comments about this anyway. By default, Mandriva 10.2 (2005LE)
installed the snd_intel8x0 driver on both my laptops (IBM Thinkpad T41 & Dell
Inspiron 600m). I could not get sound with that driver but I could get sound
with the i810_audio OSS driver. The kernel was 2.6.11-12mdk. I upgraded the
kernel in both machines to 2.6.14 which I downloaded from kernel.org. I built
the kernel without support for OSS which left me using the ALSA snd_intel8x0
driver. I still couldn't get any sound even though the driver loaded. So, I
rebuilt the kernel with module support for OSS and I got sound with the
i810_audio OSS driver. I haven't tried the latest alsa since I have a huge
rpm dependency problem trying to remove the alsa packages. I'm currently
using alsa 1.0.8-15mdk.
