For those half-duplex devices such as webcam with mic does not have "Master
Playback Volume control" 

Do wine handle this half-duplex case since windows can select prefered playback
device and capture device on two different sound card

It seem wine expect all sound cards are full-duplex 

alsa -D default is not "playback screen" of alsa -D hw:0 and "Capture Screen"
of alsa -D hw:2 because "type asym" is not supported in ctl.default
