macOS Microsoft Teams Audio Driver Issues
Raw
macos-ms-teams-audio-driver-issues.txt
In the middle of a Zoom call my audio in/out devices changed to “Microsoft Teams Audio Devices”, despite no longer having Microsoft Teams installed.
It turns out Teams leaves its audio driver on your system running, and it occasionally decides to make itself the default.
I had to delete: /Library/Audio/Plug-Ins/HAL/MSTeamsAudioDevice.driver in the end to fix it:
sudo rm -rf /Library/Audio/Plug-Ins/HAL/MSTeamsAudioDevice.driver

Charming behavior. Thank you @ziadoz!
