Mac Airplay disconnects when computer falls asleep
Recently (and this is quite a new issue for me, probably after last Apple TV update), AirPlay disconnects right when the Mac goes to sleep. Apple TV stays on, just the AirPlay connection drops. I have to manually connect the computer again (with the AirPlay icon).
It didn't happen with previous versions of Apple TV and I set the sleep time to never.
What could be the issue?
MacBook Pro with Retina display, OS X Mountain Lion (10.8.1), 16GB RAM, 512 SSD, 2.7GHz
