>Description:
Recordings made on the onboard AC97 audio system, part of the
Gigabyte GA-7VKMLS Motherboard are incorrect. WHen making
a mono recording, the track is layed down at 88200hz instead of
44100. In making a Stereo recording, one track is OK, the other
is noisy and distorted. I have tried this on two of these
motherboards. I am using the pcm driver. I have tried various
recording software.
>How-To-Repeat:
Try to make a recording.
>Fix:
Record in stereo and only use the left track for mono!
