Oh you want to use the default audio devices on your system? What default audio devices I'm going to use this random loopback device and your monitor with no speakers!
I have had to help so many end users with that it pains me.
"How can I stop this from happening again?"
Well, we can disable.other audio devices, but seeing as it's Windows 11 they may just re-enable good luck!
I ran into a user who's noise cancellation stopped working upon the rollout of "New" Teams. Tried diagnosing the microphone array, settings updates, firmware. No luck.
Know what worked? Both versions of browser based Teams!!! Ihatethemihatethemihatethem
Not the windows troubleshooter, as the mic was otherwise fine. There was nothing I could find in any Teams settings, and the admin panel showed all of the telemetry as being fine.
It's a stupid solution, but have the user download voicemod, then use voicemod as the default microphone in teams. It's stupid, but it solves all these problems.
My boss has gotten to the point of "As Ashe would say, fucking Microsoft"
Let's not forget the endless name changes, 404'd documentation that points to non existent tools all of the time, the GUI that barely works. Always an adventure
I despise these blurred backgrounds. I understand if you use it when working from home and don't have a dedicated office, but so many people do it even when they're at the corporate office. The flickering is just super annoying.
