I have a bluetooth headset. It's brand is Bluedio. I can connect the headset to my computer with no issue. However, when I disconnect my device and reconnect it again, it doesn't work as expected. Here is what is happening after reconnection; I use Kubuntu 16.04, 1) Between the first connection and disconnection of the device, I have to change the volume setting to High Fidelity Playback (A2DP Sink) (System Settings > Multimedia > Audio Volume > Configuration Tab), otherwise voice quality is suck. 2) After disconnecting and reconnecting the headset, my configuration above disappears. After reconnecting the configuration switches to Headset Head Unit (HSP/HFP), which is in the same dropdown menu with the High Fidelity Playback (A2DP Sink). However this voice quality is suck. From the same dropdown menu, if I change to the High Fidelity Playback (A2DP Sink), it doesn't change and it doesn't produce output anymore. I tried rebooting and repairring, first repairing after rebooting, first rebooting after repairing... Non. The workaround I found to this problem is deleting the associated bluetooth configuration folder with the headset. In my case, it is in the /var/lib/bluetooth. After, I repaired the headset. Reproducible: Always Steps to Reproduce: 1. Disconnect the bluetooth headset. 2. Reconnect. Actual Results: I couldn't get voice output from my headset. To be specific, I couldn't get voice output when the volume configuration is High Fidelity Playback (A2DP Sink). Expected Results: It should give me voice output in High Fidelity Playback (A2DP Sink) mode, after any kind of reconnection. I use Kubuntu 16.04.
How do you change the profile? Can you please try using pavucontrol to change the profile to A2DP after reconnecting?
confirm problem, the bluetooth headset won't output sound and Youtube won't play until remove the device from the configure window and reboot then add again temp fix: run this script every time when you have the problem https://gist.github.com/pylover/d68be364adac5f946887b85e6ed6e7ae
Confirm. Looks like the problem is specific to Bluedio headsets. I have also Philips bluetooth headset, and it is working fine.
