Hi! There,

 

I'm maintaining an HD audio driver, and meet a question about the volume
channel number.

It had two channels before, and I want to change to 4 channels.

But I don't know where will affect the volume channel number, or from where
the system gets the volume channel number.

 

Any suggestion and hint are appreciated.

B.R.

Wayne
