            Bug ID: 103941
           Summary: Offers left/right channels for device with a single
                    speaker
           Product: PulseAudio
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: core

Using the "Iqua miniUFO" in a2dp mode, only the left speaker can play anything
back in GNOME's Sound Settings. Playing back audio on the right channel doesn't
play anything.

Bizarrely, pavucontrol only sees the "Headset" port, GNOME's Sound Settings can
see both.

Is there a way to quirk the output to say that both channels need to be mixed
into the left one for this device in a2dp mode?
