How to fix audio issues in MS Teams after upgrade to Win 11

Hello community,

we are currently rolling out Win 11 (Enterprise 22H2) for our users and more and more are starting to complain about audio problems since the upgrade to Win 11.

For the most part we use Jabra Evolve 65 and 75 headsets, which are certified for Teams (they worked fine with Teams and Win 10).

Reported issues (happening in meetings and calls):

• Users mic working, but cant hear his counterpart.
• Users mic not working, but can hear his counterpart.
• No audio at all, sometimes right from the start of the call, sometimes cuts out during the call. User gets a notification that there is an issue with his audio device.
• Audio works fine but after x minutes, the call is dropped and user has restart his PC to get audio working again.

There are no audio issues with other apps like phone app or when watching a video.

We updated audio drivers, updated firmware of the audio devices. Cleared Teams cache, reinstalled Teams, made sure its running the current version. Checked windows audio settings (sometimes people manage to connect the headset via usb dongle and directly to laptops bluetooh at the same time, which can cause problems). We also asked the users to connect their headset with the usb cable instead of the dongle. Nothing helped.

I had one user working with Teams in the browser for a few days and he didnt report any problems there. So maybe its a Teams client issue?

If anyone has an idea for me on how to fix this, I would really appreciate it, since Win 11 rollout is still going on and more and more users will be affected by this. Which I am not looking forward too :)
