Try with other a2dp (stereo) headphone. Maybe [1] can tell > more.

I have a mono headset that supports HSP. When I play using aplay -D btheadset I get the following error. /Playing raw data 'Nagada Nagada.mp3' : Unsigned 8 bit, Rate 8000 Hz, Mono aplay: set_params:961: Sample format non available /But when I played using the following option aplay -D plug:btheadset the file is playing, I hear only noise.
