We may use a virtual master control when all slave controls have the identical volume resolution.
Sounds good. Is it something configurable, so there is no need to change the code?
Look at sound/core/vmaster.c.

Ok, I've tried to implement this on snd-powermac.
Takashi, looks like there is a side effect: plugging in headphone doesn't show on alsamixer, even though it works, i.e. the speaker is silenced. Or have I forgotten something in my implementation?

Richard, maybe you can try this? You should adjust Speaker and Line out to 100% in order to have full scale in Master.
