Ubuntu system. Bluetooth headset with microphone.
When the profile is set to High Fidelity Playback (A2DP Sink) audio, the sound in the headphones is stereo and excellent, but there is no microphone. If you set the Headset Head Unit (HSP / HFP) profile, then the sound becomes mono and very terrible, floating, but the microphone appears and I can be heard normally.
Help with a problem.

We won't help. A2DP does not support a microphone at the hardware level. Everywhere so.
