USB headset's microphone doesn't work on MS Teams for Mac
I have a problem with my work MacBook Air M1 (Ventura 13.6.1) audio in Microsoft Teams Classic.
When I connect a USB-C headset (Poly Blackwire 3225) no one can hear me speaking via MS Teams app. The headset is visible in macOS, and I can see levels moving in System Preferences when I speak to its microphone. The headset is also selectable in MS Teams settings but mic levels are not moving at all.
Here's what I checked/tried:
- I tried other communication apps: e.g Zoom, and Discord, and it works fine.
- I tried to use MS Teams via browser (Chrome) and it works perfectly so it seems to be related to the MS Teams desktop app.
- I checked Privacy & Security > Microphone.
- I've reinstalled MS Teams Classic.
- I used CleanMyMac X to clean junk and reset MS Teams settings.
- Just in case, I asked my company for a new headset and nothing has changed.
The problem first occurred 3-4 weeks ago and I'm constantly winning and losing this battle. Sometimes it works, sometimes not. Mostly not. I'm unable to find and document any specific conditions under which people can hear me.
Have you heard about any issue like this?
