Apple - Remove ZoomAudioDevice from Audio Devices
It appears the ZoomAudioDevice is now located in /Library/Audio/Plug-Ins/HAL/
and is no longer a kext.
To uninstall it, I deleted it with the below command and restarted.
sudo rm -r /Library/Audio/Plug-Ins/HAL/ZoomAudioDevice.driver
This is with a new install from May 2019. Perhaps old installs continue using the kext if its already installed. Though, the readme here indicates the .driver file is used on MacOS 10.10 and above.
This is from Zoom.us video conferencing software.
Here is a great explanation. I was wondering the same thing.
From the linked answer:
sudo kextunload -b zoom.us.ZoomAudioDevice
sudo rm /System/Library/Extensions/ZoomAudioDevice.kext
HISTORIC ANSWER:
See @BrezzaP 's answer for the current solutions, thanks @BrezzaP
Ah - answering my own question, it is at
/System/Library/Extensions/ .. search on "zoom"
Phew!
