Bluetooth headset cant set output as A2DP sink while using the mic as input device

[Falc]

I have the popular Sony WH-100XM3 headset.

I can connect to the headset fine using bluetooth. I set the Output device in Sound Option, there are two configurations A2DP Sink (sounds great) and HSP/HFP (sounds terrible).

If I set the input device to the headset, it silently switches the output configuration to HSP/HFP and so the audio sounds terrible.

If I then switch the output configuation back to A2DP sink, the audio output sounds good again, but then the input device switches to something else.

So the problem is that I cant use the headset as audio input while having the good-sounding output configuration.

This is unfortunately not a bug, it's the Bluetooth standard... A2DP (high quality output) does not support any input. So if you enable input you will get forced back to HSP/HFP (which does sound terrible).

But there's a solution coming in the form of a different standard, which we are tracking in bug 1838151.
