Comment 56 for bug 1576559

Hi !

I don't have the exact same problem given in the title.

I am on an Ubuntu 18.04 laptop for work and use BOSE QC 35 II headphones and more recently Sony WF-1000XM3s earbuds.

I can switch from one profile to another, A2DP Sink to HSP/HFP. However, with the A2DP profile I have stereo sound (good) but no microphone. With the HSP/HFP profile, I have mono sound (not good) with crackling but with the microphone working.

As soon as I choose my headphones/earphones in the inputs, it automatically switches the sound profile (output) of my device to HSP/HFP. If I select the A2DP profile again, it changes the microphone input to the laptop one or a usb dock (when I use one with microphone input), which is not practical if I want to take a few steps away from the laptop.

I read here and there that the A2DP was only mono-directional which explains the lack of support for the microphone.

I hope that in 2021 (it's dead for 2020), someone will find a new way to make Bluetooth devices work with a microphone on linux in stereo with good sound quality.
In my opinion, the HSP/HFP profile is no longer made for the years 2020+.
