I've just bought a Sony wh-1000xm4. I want to use audio output and microphone (headset) with the best possible audio quality for work calls (zoom, google meet, etc). The device connected automatically in the first start, and I can hear really good audio with this configuration:

A2DP Sink

Then, when I configure to use the Sony wh-1000xm4 microphone for calls, the audio sounds horrible but the mic works:

HSP/HFP

I've read that A2DP Sink doesn't have a mic input mode. Is it any other way to configure both audio output and the microphone in a good audio quality configuration? This is my setup:

  • My laptop is a ThinkPad L15 Gen 2 (15" Intel).
  • Connectivity • WLAN + Bluetooth: RTL8852AE 11ax, 2x2 + BT5.2
  • My Ubuntu version is 20.04

As of now the answer is sadly: No. Your operating system needs to choose a Bluetooth profile. HFP is the standard for using the microphone. This is also mentioned in Sony documentation.

So it is some kind of Bluetooth technology problem. This is also answered in detail in https://superuser.com/questions/1101560/bluetooth-handsfree-better-quality
