I got my Apple TV a year ago as gift. I was mirroring from my Macbook Air ok until today. I can mirror video but the sound stay on my Mac.
When I use Airplay, I can mirror video from my Macbook Air but there was no sound from TV (the sound on my Air still on). I had use my Mac to do Airplay for six months without problem until now. My wife can use her iPad-4 to watch TV with Airply fine without the sound problem. My Macbook Air was purchased in summer of 2011 running Marverick at the moment. Can you help?
