[Daniel van Vugt]

I have sound-theme-freedesktop (0.8-1ubuntu1) installed and still get
white noise. Is something still missing?

Title:
  Dedicated mono test sound is unavailable

Status in sound-theme-freedesktop package in Ubuntu:
  Fix Released

Bug description:
  When testing stereo speakers you get the "Front left" and "Front
  right" samples, but no such sample exists for mono speakers e.g.
  HSP/HFP bluetooth devices.

  Instead you get played the "audio-test-signal" which is white noise.
  To begin with I thought this was a problem with Bluetooth or the
  speaker itself, but it's just the sample being used.

  There is a bug upstream to provide this sample, but in the meantime I
  think playing the "audio-channel-front-center.oga" is a suitable
  standin.
