REMOVING DEVICE ENTRIES IN WINDOWS
Press Win+R, and then write "regedit" in the box, and then press OK to open the Registry Editor.
Navigate to this key (a key is like a folder):
Here you see subkeys that are in this format:
The xxxx is the product ID. See below for more information*
The yyyy is the unique ID of your particular device.
Right-click the device you want to remove and select "Delete" Do this for all subkeys related to your device
REMOVING DEVICE ENTRIES IN MACOS
This will delete all known devices from the ControlPanel and the CoreAudio plugin.
Start a terminal session.
Unload coreaudio daemon (or else you will not be able to move the coreaudio plist files)
sudo launchctl unload /System/Library/LaunchDaemons/com.apple.audio.coreaudiod.plist
sudo killall coreaudiod
The second line is just in case the first one doesn't work.
Move / delete the plist files to another location:
sudo mv /Library/Preferences/Audio/com.apple.audio.DeviceSettings.plist ~/Desktop/PlistBackup/
sudo mv /Library/Preferences/Audio/com.apple.audio.SystemSettings.plist ~/Desktop/PlistBackup/
sudo mv ~/Library/Preferences/se.elektron.OverbridgeControlPanel.plist ~/Desktop/PlistBackup/
sudo mv ~/Library/Preferences/se.elektron.overbridge.hal.plist ~/Desktop/PlistBackup/
Remove PlistBackup folder on your desktop.
