Greetings -

I have an ABIT AN7 motherboard with an nForce2 audio controller.  The
AC97 chip is an ALC658, and the patch from ac97_patch.c from 1.30 to
1.31 in CVS seems to have broken standard stereo output.  I can get some
sound output from my speakers if I enable Line-In As Surround and
Duplicate Front, but it is very faint.  Without these features enabled,
I don't get any audio output from any of the analog output jacks.

I've looked at the code, for patch_alc655() as compared to
patch_alc650() but I'm not proficient enough to figure out what to
change to make it work, so I've simply modified ac97_codec.c to use
patch_alc650() for my ALC658.  There seem to be other people on the
alsa-users list with a similar problem, and I'd be happy to help try and
diagnose the problem further, but I'm not sure what other information
will be helpful.

TIA
David Van Duzer
