Public bug reported: Hi,
Trying to connect a JBL-450BT heeadset to my system has resulted in several bugs. The particular one I have encountered is that audio settings are silently discarded if the user is not a member of the audio group. the particular settings I was trying to fiddle with were the headset profile (A2DP -> HSP/HFP) and the mic input. Steps to reproduce: 1. Install ubuntu 20.04 desktop, making no particular add-on or configuration actions. 2. Connect a bluetooth headset using the system UI. 3. Go to sound settings, change the connection profile from A2DP to HSP/HFP. Expected result: Upon closing the settings app, the settings activate and the profile switches to HSP/HFP. upon reopening the settings app, settings are preserved. Observed result: Upon closing the settings app, the settings do not activate and the headset remains on A2DP profile. upon reopening the settings app, settings have been reverted / not been saved. Observed result 2: Adding the user to the audio group and rebooting the machine has caused the problem to disappear and behaviour now matches 'expected result'. this is apparently against https://wiki.ubuntu.com/Audio/TheAudioGroup . I have to say I'm stymied about which package this needs to be reported against.
