Managing sound and video settings during Teams meetings and calls
well, in my case I found the culprit. It was the bluetooth connection of the Withings Smartwatch which blocked not only Teams but also disabled the bluetooth connection to my car. Interesting enough is that apart from Teams and Phone, all other bluetootha applications were not in trouble, so I could listen to spotify, youtube and otehr music on my phone with bluetooth, but as said, Teams stopped working on Bluetooth. Very mysterious. Just deleting the bluetooth connection to the Withings watch was not enough though. I had to reset the watch to make sure it would not attempt connecting. Once the bluetooth pairing on both sides was gone, Teams worked again without trouble with all bluetooth devices. I really don;t know who's to blame, Micrsoft or Withings.
