Description
Currently we have sounds to tests speakers for front center, light, right and so on, that will be used by e.g. gnome-control-center's sound setting to test speakers. For mono speaker test (i.e. bluetooth headsets HFP/FSP) audio-test-signal.oga is used, which can easily be mistaken as broken audio (hint: I did). It would be nice to have a dedicated mono test file.
