hdaudio(4) mixer small oddity

[Nicolas Joly <njoly%pasteur.fr@localhost>]

Hi,

I tested the new hdaudio(4) on my Sony VAIO laptop and noticed that
setting volume with mixerctl do show some unexpected results ...

Setting outputs.master/inputs.dac values from 0 to 63 make the sound
volume increase, but at 64 it suddenly becomes silent and then
increase again up to 127, etc ...

Looks like there is a range conversion problem when converting mixer
values to raw ones for setting the codec pins.
