Public bug reported:
Lsusb ID: 046d:0a1b
...as well as another I have at home, has just a "speaker" mixer control and
nothing else, which seems to confuse PA into believing it can't control volume
at all. We probably need an udev rule and a separate mixer profile to solve it.
Relevant part of pulseverbose.log follows.
