AppleTV Airplay audio fails
When I use Airplay to create a separate display via my AppleTV at first everything is fine, but after a few minutes the audio gives out a short burst of distortion and then vanishes. I can switch to another output source, such as my Mac-Mini or display speakers, and the audio returns. I then return the output to the AppleTV and after a period of normal output (2-3 minutes) it fails.
