 | Hi,
 | 
 | I've come up with an alternative.  See attached.
 | 
 | In this patch audioctl devices default to the mix ring allowig hw gain to be 
 | adjusted (recording/ play back/ balance).  If one were to issue audioctl 
 | without specifing -p vchan it would set the hw paramaters one could still issue 
 | audioctl -p 0 to achieve the same thing.
 | 
 | It would mean existing sun audio apps that set the master volume via 
 | play/record->gain would not have to be changed and nor would scripts that want 
 | to set the hw gain via audioctl(1) and don't specify the -p swich have to be 
 | changed.
 
 Sounds good!
