  -----------
  Improve USB audio mixer support for USB audio
class 1 and 2. - make sure volume controls are correctly mapped to "pcm" and
"rec" depending   on how they deliver audio to the USB host. - make sure
there are no duplicate record selections. - remove internal only mixer class
type. - don't add software volume controls for recording only. - some minor
mixer code cleanup.
