There is a MAJOR problem with the current alsa mixer.
How do I set a mixer volume to the 0 db point. I.E. no attenuation, and no gain.
Currently, we might have a value from 0 to 100%. Percent of what?
What this value means varies depending on the sound card hardware being used.
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.


Cheers
James
