Subject: [PATCH 3.5 02/71] ALSA: oxygen: Xonar DG(X): modify DAC routing

3.5.7.33 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Clemens Ladisch <clemens@...isch.de>

commit 1f91ecc14deea9461aca93273d78871ec4d98fcd upstream.

When selecting the audio output destinations (headphones, FP headphones,
multichannel output), unnecessary I2S channels are digitally muted to
avoid invalid signal levels on the other outputs.
