How to uninstall Core Audio Driver (MSTeamsAudioDevice.driver) in m1 macOS Microsoft Teams Intel Architecture Processes

With the ms teams update that came in June 2022, the same intel architecture process appeared in the background for me. Even though I uninstalled ms teams it was still there. When I removed it from the audio state folder, that MSTeamsAudioDevice.driver process didn’t start automatically. It’s much more logical to use ms teams as pwa on chrome for m1’s, unlike the intel msteams app, it won’t use excessive battery.

Core Audio Driver (MSTeamsAudioDevice.driver) running as an Intel process on my M1 based macOS.

I had to delete:

Code:

/Library/Audio/Plug-Ins/HAL/MSTeamsAudioDevice.driver
/Library/Audio/Plug-Ins/HAL/MSTeamsAudioDevice.driver/Contents/MacOS/MSTeamsAudioDevice

and force kill the process. (You can access hidden library folder by holding option key on Finder and click “go” in menu. Then u will see library.)

Advice: Uninstall MS Teams app and install PWA of MS Teams through Chrome.
