[alsa-devel] [PATCH] ASoC: TWL4030: Use codec defaults for Headset initial configuration

[Peter Ujfalusi]

Disable the amplifiers for the headset outputs, and do not select
routings by default to the headset outputs.

The obvious side effect of this patch is that on boards which are using the
headset output the playback will not work 'out of box'.
The user need to specifically enable the routings for the boards.
Board that came to my mind is the Beagle, and probably it's clones as well.
