No sound on Mac after using Apple TV

Did you make sure your Output Device is 'internal speakers' and not 'Apple TV'?

iTunes?

Greetings,

Open iTunes. Look in the Bottom right for an icon. This icon controls sound for your mac or apple tv. Just select your computer. Sorted.

Yes, this caught me out, too.

If you are running iTunes 11, the icon has moved to the top of the screen - next to the play button. Click on it and make sure that the local output is selected.

go to settings/audio/output ,make sure is on internal speakers.

I know that this thread is a bit old; but I had the same problem with my setup. Have a Atv 3 connected to a Samsung Tv. Streaming movies through my Mac would work; however, there was no sound; only video at the Tv. There was sound at my computer. If I played a movie through iTunes; everything would work as it should. If I tried streaming a movie through Xbmc; or played a movie through a third party player; I would get video; but no sound. I did a search for this problem and came up with several pages of different solutions; none of them worked. What I did try was; on the Atv 3; go into settings; Audio and Video and Output. Changed the setting from “Auto” to “16 Bit”. This worked for me! (For now).

Just thought I would post this; just in case it may help someone out.

This happens to me too. I ended up just going to the volume icon in the upper right hand corner and turning it up. I guess you can say that I just deal with it.
