Try to remember if you installed something that could have added it and if you uninstalling the application properly should get rid of this.

If not try looking in /System/Library/Extensions/, /Library/Extensions/, /System/Library/PreferencePanes and /Library/PreferencePanes to see if you can find files related to it.

Take a look in Audio Midi Setup. Something may be in there. Alternatively, is the erroneous device broadcasting rather than listed? It might be an airdrop device. Just a thought...?

what randomgeeza said. try turning off wifi, bluetooth. still there? def then a visit to the audio midi setup (in your utilities folder); check the audio devices there.

I checked with everything off, still there.
"UI sounds" (ie 'user interface sounds') suggests this is for an app; something you must have installed. can you delete those listings from that audio midi setup window?

EDIT: what brian suggests, above. try the free 'easyfind' app (on the app store), and you can search your entire drive (be cautious with what you remove)...

On my Mac Pro, MM Audio Device refers to some external speakers I am using. Selecting it enables the speakers.

The driver should be in the "/Library/Audio/Plug-Ins/HAL" folder (It's the standard place for Core audio drivers)
Thanks, That did it for me. I was trying to get Sound Booster off of my device list.

This sounds like the answer to my issue, as well. Where do I find "/library/audio/plug-ins/HAL" ? I can't find it on my early 2015 Macbook Air with Mojave 10.14.5.

Thanks!

Library folder is at the root of your hard drive, along with Applications, System, and Users.
So, Open the Library folder, then the Audio folder, then Plug-ins. There should be a HAL folder. Open that folder.
If you find a MMAudio Device, or MMAudio Device.driver folder - you can delete that folder. You may have to provide your admin password to remove it, but that should do it. Restart after deleting that folder.

Found it. Turns out my hard drive was not displaying in the side bar, but I was able to change that and then access the HAL folder. Thanks for your help!
