Did you try yo use snd_hda_intel?
Run
Code:
modprobe snd_hda_intel
and then try to configure sound using alsconf/alsamixer or yast.

I had no reason to know to try anything.
Anyway, I did the mod probe and did the alsaconf.
Still no joy. "modinfo" on the driver afterwards
yields:

It is modprobe not mod probe. The module is snd-hda-intel. This module supports a lot of integrated sound cards including ATI and nVidia, so you may have to force it to one model.

The list can be found in ALSA source code or in the kernel source code. Do a search for "ALSA-Configuration.txt".

MCP51 will not run under Kernel 2.6.13. I have the same audio in my 64 bit motherboard. It didn't work till I installed Sidux 2007_02 or the new SimplyMepis Beta. Both had kernels later than 2.6.21.

I did the module probe by typing the "modprobe" command. Thank you. ``Both had kernels later than 2.6.21'' -- Rats. ``The list can be found in ALSA source code'' Double rats. The next several weekends are scheduled. I'll have to resume this much struggle come October. Thanks for your tips! Regards - Bruce

Hi all. Thank you all for your help. I've now tried several recent distributions, and they all hang on ``starting udev''. I've probed far enough to know that adding the boot option, ``acpi=off'' gets me past the problem. Sure enough, it does. It just leaves my disks invisible; making it hard to re-install. From what I can tell, this problem has existed since May of 2006 and there is still no fix. So, until the udev is either fixed or restored to the working pre-May 2006 version, I'm hosed.
