Bluetooth Headset not working with teams.

Ive spent so much time trying to figure this out. Luckily I have an IT friend and after 3 days of trying I can finally hear my company calls again with my bluetooth headphones. To fix this, you need to be in a teams call. You will not be able to hear anyone obviously but once are you in a call and the sound has cut off.

Go to bluetooth and devices

scroll down under related setting click on more devices and printer setttings.

It will then bring up a screen with your devices.

Click on your bluetooth headphones.

Click on the services tab.

Unselect (remove checkmark) from handsfree telephony.

Hit apply and ok

Your teams will now have sound!

I saw this fix but it did not work for me but I tried it as a last resort while in a teams call and that is what got me over the hump. YOU HAVE TO BE IN A TEAMS CALL FOR IT TO WORK

Thank you! This did it for me, combined with ensuring none of the other fixes listed were in place. I.e. I had to make sure LE Bluetooth Enumerator was enabled.

I then disabled telephony, unpaired and re-paired the headset. Teams now uses the correct audio channel for my headset to be able to listen to system sounds (mostly spotify...) and the call at the same time.

Oddly, I cannot re-enable Handsfree telephony:

Windows 10, using M&D MW65

I had the same issue and fixed it.

However, before going forward be aware that I think this is a limitation of how Bluetooth audio works on Windows. My understanding is that the "headset" option provides lower audio quality to free up bandwidth for the microphone data. The "stereo" option uses higher quality audio, but as a result the microphone can't be used. If you want to use the stereo option, you need a microphone separate from your headset. Again, this is just my limited understanding of how it works.

Teams seems to handle the switchover between the two... inelegantly. If you want to force Teams to use the stereo option and a separate microphone, this worked for me:

1. With your headset connected, hit the start menu, type "control panel" and open it.
2. Click sound
3. Under the playback tab, find the stereo version of your headset. If it's disabled, right click, enable. Right click it, and select "set as default communications device". Do this again for "set as default device". 
4. Find the "headset" version of your device, and right click -> disable.
5. Go to the recording tab, and find the microphone you want to use. Right click it, make sure it's enabled, and select "set as default communications device". Do this again for "set as default device". 
6. Under the same tab, disable the headset.

If you do all of these things, the headset shouldn't show up in Teams and audio should be successfully sent to the stereo version of the headphones. I found that if I didn't set the default devices correctly, it would still be trying to read the microphone data from the headset even when I had selected an external microphone in Teams. This then disabled the stereo option - resulting in no sound.

This worked for me in Windows 11.

Control Panel >> Sound >> Playback >> BT Headphones >> Properties >> Advanced >> (Untick) "Enable audio enhancements"

This made the headphones work in Teams, and stopped the BT stack from crashing. But I still had no microphone on a test call.

To solve that:

Control Panel >> Sound >> Recording >> Headset >> Properties >> Advanced (Untick) "Allow applications to take exclusive control of this device"

After these two changes were made, Teams seems to be working as expected.

I have had this happen almost consistently for about 3 weeks now, after about 5-10 minutes of working, the headset stops working. I've tried 3 different headsets and changing the settings makes no difference. This seems to be some sort of issue within teams.
