I hear distortions on my Burr-Brown USB DAC whenever the (software) volume is set to some value lower than 100% in mpd. The lower the volume the bigger are the resulting distortions.

see patch: http://marc.info/?l=linux-kernel&m=133905533312625&w=2

You're probably getting distortion because mpd decided it would use a stream format that's only 8bit.

Yes. The patch fixes the issue. Many thanks.

The patch is already in sound git tree, but missed in rc2. It should be in rc3.

thanks,
