There are two ways how to delete JustStream Audio Driver:

  1. Open Terminal and execute the following commands in sequence:

    sudo rm -rf /Library/Audio/Plug-Ins/HAL/JustStreamAudioDriver.driver

    Prior to macOS 14.0:

    sudo launchctl kickstart -k system/com.apple.audio.coreaudiod || sudo launchctl kill SIGTERM system/com.apple.audio.coreaudiod || sudo killall coreaudiod

    In macOS 14.0 and later:

    sudo killall -9 coreaudiod

  2. Or just simply delete JustStreamAudioDriver.driver from the folder /Library/Audio/Plug-Ins/HAL/ and reboot your Mac.
