I have Apple TV along with an iMac. I mainly use it to mirror my iMac. I have movies or tv shows on my iMac. And instead of watching it on there, I mirror to my Apple TV. Never had an issue. Audio would come out of my tv as well when mirriorig. Earlier this week, I tried to connect to my Apple TV to mirror. When I did the first step, to connect it on my iMac, I noticed a number 2 popped up next to Apple TV. So now it says: apple tv(2) Not sure why the number 2 popped up? But I continued. It would mirror like normal, visually. But the sound wasn't coming from my television?? It was coming from my computer? Very annoying beCause I didn't change any settings? Thoughts anyone??
