There is no audio.conf in my /etc tree. The
bluez-audio is configured here /etc/alsa/bluetooth.conf (attached).
Tarball /etc/bluetooth is attached too. But, telephony-dummy is a2dp
device ? Try with other a2dp (stereo) headphone. Maybe [1] can tell
more. And try a simple "aplay -D bths foo.wav" for testing (where bths
is your entry in ~/.aosundrc.

I have same bluetooth.conf file.

I had one audio.conf in the /etc/bluetooth which I deleted and tried.
The device connects
in HFP and only noise we could hear.

I do not have a stereo headphone. I have a mono headset that supports
HSP. When I play
using aplay -D btheadset <music file> 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 <music file>
the file is playing, I hear only noise.
Thanks & Regards,
