3.2.56-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Clemens Ladisch <clem...@ladisch.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.
