MJRecorder Audio Device I have been using Sound Source to control app specific volume on my iMac 2017. This app shows two separate audio devices - Headphones and MJRecorder Recorder Device. Any idea where this MJRecorder Device came from and which app installed this is an audio device?

I would want to remove this if it is not a default system audio device.

Any help is much appreciated.
Someone on Apple Discussions recommended you Delete "MJRecorderDevice.driver" located in /Library/Audio/Plug-Ins/HAL then reboot your system.
