Teams for linux bluetooth headset mic not working

Question

I am running Elementary OS 5.1 (Hera) - Ubuntu 18.04.3 LTS and Teams seems to work ok so far, except with my bluetooth headset. It routes the audio to the headset fine, but the microphone always is from my laptop not from the headset. It also seems a bit unstable...sometimes it works on my headset and sometimes Teams locks up and crashes.

Any help would be greatly appreciated. Here is my card info:

Answer 1

When I start Teams for Linux, it automatically switches my Bluetooth headset to HFP

This is actually something I really do not like.
On HFP, Bluetooth sound is basically useless.

I think it is better to keep it on A2DP and use a separate mic as input.

Is there a way to turn this off?

Answer 2

I have the same issue. I cannot use Teams with Bluetooth speakers or microphones under Ubuntu Linux.
My workaround is to boot into Windows to use Teams, which means I take a huge productivity hit.

Teams on Linux is definitely not equivalent to Windows, that's for sure.

I have the same problem with Teams. It recognizes my Bluetooth headset, but the sound and microphone are no longer working after entering a meeting. I hear sounds from other applications on the same machine, just not from Teams.

The workaround I perform now is to start a Skype meeting where I mute my sound and microphone and then enter the Teams meeting. Somehow this way my headset keeps on working during the Teams meeting.

I have no idea why this is working, but it does! For reference, I am using Fedora 37, with Xorg11 as graphics platform and my headset is a Sennheiser PXC 550-II Wireless.

I am using the latest version of the (very limited version on linux) desktop version of Teams

Answer 4

I'd like to follow this topic and as well need resolution.

With A2DP, I cannot use my mic, but can hear others.

With HSP/HFP, I can only hear the left channel, and from browser, I couldn't even be heard by others. Of course, quality is low.
