Additional settings-related features and issues within Microsoft Teams for business
I have the same issue, and I'm pretty sure KB5066835 is to blame, as prior to this I had no problems at all. I can hear audio just fine from YouTube or similar, but no bluetooth headset microphone will work and Teams is refusing to pipe any sound at all to Bluetooth headsets or use the microphone. I have tried re-pairing, the trouble shooters (although Windows 11 claims that I don't even have half the troubleshooters and at one point claimed I don't have a bluetooth radio which is patent nonsense). Windows 11 is amateur hour writ large; the worst OS I've had the misfortune to use (and that includes Windows ME and 8). This the same with:
Pixel Buds Pro
Pixel Buds 2a
Bose QC 35 II
Having to use a tethered headset without noise cancelling is not just inconvenient, it's utterly absurd. Bluetooth is not a new technology, but apparently Satya's push to replace humans with shit AI is now bearing fruit in the number of crappy, broken updates being shipped to users who have no choice but to stick with your dreadful OS because of work. Not that he'll care what with his fat paycheque, bonuses and shares of course.
