I'm using the built-in sound hardware on a Biostar PT880 Pro-A7C motherboard
with an auxiliary SPDIF bracket (the motherboard just has an SPDIF header).
This motherboard uses a VIA 8237R chipset for audio functions. I'm using the
32-bit Ubuntu 6.10 with a locally-compiled 18.104.22.168 kernel. The 2.6.17 kernel
that shipped with Ubuntu 6.10 worked for 2-channel sound out the SPDIF
connector, but I couldn't get MythTV to output 5.1-channel sound with that
configuration. The 22.214.171.124 and 126.96.36.199 kernels seem to have fixed that. (I
haven't tried anything in-between Ubuntu's 2.6.17 and the generic 188.8.131.52
Note that getting 5.1 sound working can be frustrating, since there are quirky
hardware-specific mixer and perhaps even MythTV settings needed. It's
possible that you'll be able to get your card working, but I can't offer
specific suggestions for your hardware. Best of luck with your current
hardware or whatever you get to replace it.
