Headset Configuration Automatically Changes From High Fidelity Playback (A2DP Sink) to Headset Head Unit(HSP/HFB)

  • 772

I just installed ubuntu 20.04 and was using Bluetooth headset with it. The sound at first was all right but whenever I change the microphone (input) device to headset the output configuration changes to Headset Head Unit(HSP/HFB). It actually doesn't show the changes but the sound quality is clearly noticeable. And when I try to change the output configuration back to High Fidelity Playback (A2DP Sink), the input device automatically changes to Headset Microphone - Built-in Audio.

So, is there a way I can get both output configuration to High Fidelity Playback (A2DP Sink) and input device to Headset?

Any Help Would be Appreciated!

  1. I think this is probably the same issue as this one.

    To summarize:

    Basically you need to change this line in the file /etc/pulse/default.pa:

    ### Automatically load driver modules for Bluetooth hardware
ifexists module-bluetooth-policy.so
load-module module-bluetooth-policy
.endif

    to

    ### Automatically load driver modules for Bluetooth hardware
ifexists module-bluetooth-policy.so
load-module module-bluetooth-policy auto_switch=false
.endif
