[alsa-devel] simplest volume control possible

[John Kacur]

I'm looking at the dapm.txt documentation, and I'm looking at the code
in codecs like wm8753.c, and I'm thinking that all of this is
tremendous overkill for the very simple codec I have. Basically I
don't care about power, the thing can be powered on all the time. I
put a one pulse on a gpio for volume up and a zero pulse on a gpio for
volume down, 0 - 63 pulses though.

Question, then, what would be an appropriate widget to use?
