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 being 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.
