Re: VIA82c686a sound problem

The via82c686.c code changed this week to implement the cold reset described 
in the AC97 r2.3 spec since there are some boards where the former 
initialization does not work.  It may be your board is reporting it's ready, 
but it requires a reset.  Can you apply the attached patch to the head version 
of via82c686.c and let me know if it works on your h/w and what the additional 
dmesg information is?

The patch forces a cold reset and sets an additional "enabled" bit in the AC97 
link control register during the reset (there's not enough info in the spec to 
know whether this bit should be set during the reset, it works elsewhere).
