[alsa-devel] [PATCH] ASoC: WM8903: Fix Digital Capture Volume range

Tue May 10 00:32:03 CEST 2011


Increase the range of the Digital Capture Volume control to be 120 steps.
Each step is 0.75dB, and the range starts at -72dB, giving a max setting
of 18dB, which matches the latest datasheet, to the precision of the step
size.

Tested-on: Seaboard non-clamshell.
