These are instructions about your chip from the latest alsa driver
snapshot.  That snapshot is available here:

ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz

Thanks for the reply. I've downloaded, untarred, and am reading.
So far, I don't see anything, but there's a lot there.

Also, I note that /dev/dsp exists, but if I copy some file to it, no
sound comes out. I wonder if that's related.


  Module snd-via82xx
  ------------------

    Module for AC'97 motherboards based on VIA 82C686A/686B, 8233,
    8233A, 8233C, 8235, 8237 (south) bridge.

    mpu_port	- 0x300,0x310,0x320,0x330, otherwise obtain BIOS
    setup [VIA686A/686B only]

How does one pass these things in? Would I have to edit /etc/module.conf
or some /etc/rc.d or sth like that? I'll reboot and see what the BIOS
says the port is. Hmm. It says only for VIA686A. I guess not applicable.

You could also run the script below and post the link or run with option
(I think it is) --with-noupload and post the output so people can see
what your system configuration is.

http://www.alsa-project.org/alsa-info.sh

I ran that script, and captured the output, but it's nearly 800 lines
of stuff, and not suitable just to post. However, if anyone knows
how to interpret it, and can help, then I can subset out what is
useful. At least these parts seemed useful:

I don't have that card so it is hard for me to offer any concrete

Thanks so much for what you were able to offer!
