I'm talking about this:Or are you not talking about airplay display mirroring.
Is it possible to mirror video from my iMac to Apple TV, but still have the sound coming from my iMac headphone port, and not my TV?
My rMBP 10.8.3 does this now. In fact I was trying to figure out how to get the sound to the ATV. No sound regardless of how the sound out is configured (sound only plays on the rMBP). Or are you not talking about airplay display mirroring.
So its possible as my rMBP does this by default.
I had same problem before, just restart your MBP. You can always select sound output source at the system preferences.
