Issue Description:
Specific codecs do not correctly support Input Enable
and Output Enable pin widget controls. This results in an
attempt to shut off the pin, and it doesn't shut off. The
Microsoft audio class driver has other ways of making
sure the pins don't make sound, which happen to work
for these specific codecs.
