You can do if your Apple TV is playing via AirPlay no sound
Often the Problem occurs when a Film is started before the AirPlay Mirroring:
- Disable AirPlay and pause the Video.
- Select AirPlay again, and then let the movie continue to run.

A Possible Interfering Factor: MacKeeper
Often the Software is blocking MacKeeper the Airplay Signal:
- MacKeeper install often unknowingly together with other programs. MacKeeper is landed only once on your Mac, the Software starts normally, with your Computer.
- You look in the task bar at the top right of whether or not MacKeeper is active. Do you recognize the program to the icon with the robot head. MacKeeper is running, quit it, as long as you AirPlay want to use. The works, by clicking with two fingers on the icon and choosing Exit.
- If you have the program unknowingly loaded and might not need it, you can MacKeeper and uninstall. In a further practical tip we show how this works.
If nothing helps, start the Mac and Apple TV-new
Both ways do not work, you can try to fix the Problem by a reboot. Apple TV start by doing the following:
- You go to the top right of the "settings".
- Select "General" and then at the very bottom of the "reboot".
