>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!

 I have since installed FreeBSD 5.1 on the same motherboard with the 
 VIA AC97 sound hardware. I used the pcm driver here also.
 
 On 5.1, the recordings are off speed slightly. The apparent pitch of 
 the playback is down aprox 5%.
