[PATCH 3.11 003/144] ALSA: oxygen: Xonar DG(X): modify DAC routing

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

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

From: Clemens Ladisch <clemens@xxxxxxxxxx>

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.
