I put Ubuntu 18.04-2 on a USB driver and booted up. I got slightly different behavior:
1. When I first paired the headphones with my laptop the audio profile was High Fidelity Playback (A2DP Sink) and everything sounded good. 2. When I turned off the headphones, waited for the Bluetooth devices window to say the headphones had been disconnected and then powered the headphones back on and waited for them to auto-connect the audio profile was Headset Head Unit (HSP/HFP) and all sound was in mono. 3. If I disconnected the headphones using the Bluetooth devices window and then reconnected the headphones using the Bluetooth devices window the audio profile was High Fidelity Playback (A2DP Sink) and the sound was in stereo. I removed blueman from my Mint system and still experience the original issue. Here's what I have installed on my Mint system: $ apt list --installed | grep blue WARNING: apt does not have a stable CLI interface.
