Using Microsoft Teams on macOS, including installation, features, and compatibility
I spent 2.5 hours yesterday doing allll of the steps I've found in every forum and I think rolling back the intel bluetooth driver worked for me. I did a test run with teams, Settings > Devices > Make a test call, and everything worked for the first time since this all started a few months back. I havent had an actual teams call to test it but this is promising. I think some things work for some people, and others work for some, its not a one fix works for all type of thing.
Windows Key + X > Device Manager > Bluetooth > Intel Wireless Bluetooth > Driver > Rollback Driver. Restart Windows. I also restarted my airpods before I rebooted, and re-connected them to windrows to have a clean slate on both accounts. Then made my test call with teams and it worked.
