Subject: [Bisected] ALSA: snd-usb: New streaming logic causes distortions on Burr-Brown DAC
Date: Fri, 8 Jun 2012 18:40:04 +0200	[thread overview]
Message-ID: <20120608164004.GA580@x4> (raw)

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.

I've bisected this to the two commits below:
(One wouldn't compile without the other)
