It might have a value from 0 to 100%. Percent of what? I think that this should all be changed to signed values, with a max and a min setting. With a value of 0 being equivalent to no-gain, no-attenuation. Each alsa-driver would then convert this signed value into a value actually written to the hardware register via a lookup table.
