I am using this piece of code (below) to get it work. ![]() So I need to stop and restart CoreAudio daemon. I found out that when the music is playing using this device then sometimes it is not possible to get access. # On a macOS system which has proctools installed, you can replace `killall` to `pkill`īlueutil is cool stuff, but it is using some private APIs of amework, so it may not work on the future version of macOS.I am developing an app which needs to have exclusive access to the USB sound device. $ sudo killall -HUP bluetoothd # or blued based on macOS version Library/Preferences/ ControllerPowerState -int 0 Library/Preferences/ ControllerPowerState -int 1 Sometimes this problem can happening without reason at all and come back. Continue holding these keys until computer restarts for 4 times, then release those keys and allow to restart normally. You can stop the service using the 'unload' subcommand.
