How to remove audio devices on macOS

I have quite a lot of equipment in my home office, connected to my Mac Studio.

This results in a number of audio devices available for selection, that I will never use - eg the speakers embedded in any of my 5 monitors.

To remove audio devices is not a readily available option on macOS.

Neither in Preferences > Sound, nore in Audio MIDI Setup > Audio Devices.

One solution for audio devices installed as plugins is:

  • use Finder: Go > Go to folder... and type /Library/Audio (not ~/Library/Audio which is the User's folder, not the root folder)
  • navigate to Plugins > HAL and delete devices that have been added there as needed
  • restart macOS

Still looking for a solution to remove audio devices from hardware devices (eg the monitors).
