Public bug reported:
This system comes with a combo audio plug (headphone/mic) and accepts
the 4 band apple plug headsets. However, only output seems to work. On
plugging in a headset that is known working hardware, the external audio
becomes a selectable source in the sound config tool for output, but
input only shows the internal mic available.
