SubjectRe: SiS/Trident 4DWave sound driver oops
From
Date
Quick summary: sound now works on the ALi 5451 chip, 
but has some non-fatal error messages.

I just removed that final data set and the preceeding comma and
recompiled 2.4.12-ac6. I'm pleased to report that the sound now works
just fine! The module loads, and I do get some (non-fatal) error
messages, but once its loaded it runs like a champ.

BTW, I was also getting these error messages on my old 2.4.7 install.
This is my 2.4.12-ac6 log after `modprobe trident`. Take a look:

This hangs the system totally for about 5 seconds. After this, it's all
fine and the sound works great. One strange thing I notice from the
above log is the different codec IDs showing up...

Thanks,
