I want to use an AppleTV using AirPlay (AppleMusic) for music listening. I won't be hooking it up to a tv, but I can temporarily hook one up for set up. It would just be there in case I want to listen to music and stream music. The reasons I want to do things this way are complicated. I have a TOSLINK-compatible DAC that I particularly like the sound of and I want to hook it up to some headphones without having to tether down my MacBook Pro. Is this possible?
