These are the controls for the master channel.

    bmaControls( 1)      0x03
      Mute Control
      Volume Control

These are the controls for the mic's left channel.

    iFeature                0

The controls for the mic's right channel are missing.

There are no descriptors for playback, but this does not matter for the mixer.
