Hi everyone, i'm pondering a rather obscure question: I want to Airplay Mirror the content of my MBA to the Apple TV, but without a television attached to the Apple TV, effectively just "mirroring" the audio (via optical output). So my setup would be like this: MBA -> Apple TV -> optical cable only (no HDMI) -> DAC/stereo. Is this possible? This way I could not only stream music from iTunes to my stereo, but also music that is played on Youtube/Vimeo etc. Thanks!
