Microsoft Teams Causing Audio Dropout?

I'm on a 2023 MacBook Pro 16" (M2 Max), running Sonoma 14.5. I have an audio issue that's been happening intermittently, but seems to be narrowed down to this scenario:

Audio (input and output) works fine system-wide, and for Zoom/Skype/FaceTime.

I participate in a MS Teams call, either through the web interface or the desktop version, and the audio works fine.

AFTER any MS Teams call, my audio output volume drops (to like a 6 out of 10?) and my audio input is so low that no one can hear me on calls -- like Zoom or FaceTime. What's odd is the sliders in System Settings haven't moved, but the entire system responds as if I've turned them down to zero -- as in, the little mic indicator doesn't react to my voice at all.

It seems like once I use Teams, the audio locks up somehow, or Teams itself takes my audio settings over. I really noticed it because I haven't had the issue for days, but today was my first Teams call in a week. Immediately after that call I had a Zoom meeting and my audio wasn't working again.

So far, the only way I've been able to get it working again is to reboot the machine, but obviously it's inconvenient to reboot every time I have a meeting. Has anyone else noticed this issue, and more importantly, has anyone come up with a permanent solution?

Looking forward to hearing your input, gang.
