No Sound with AirPlay Extended Desktop on Mavericks

Been running into an annoying intermittent issue with AirPlay’s extended desktop feature where sound is not being played by the TV, it just continues to use the laptop’s built-in speakers. Restarting the laptop fixes the issue but that is annoying so after some digging I was able to find that the service “coreaudiod” is the one responsible streaming the sound (and possibly AirPlay all together, killing it breaks the connection to the Apple TV).

Just kill the coreaudiod process with Activity Monitor, restart AirPlay extended desktop, and that’s it, back to enjoying your talkies!
