Stream iTunes to AV receiver
Hi. I have music library on my desktop in my room and I would like to wirelessly stream it to my AV receiver in my living room, using my iPad Air 2 as a some sort of remote controller. The receiver is not connected to any wireless devices (no AirPlay, AirPort, Bluetooth, etc) except Chromecast, and speakers are just regular wired ones, nothing fancy. Also the TV is not any kind of smart TV.
At first, I was thinking of getting Bluetooth adaptor (like Logitech one) and connect it to the receiver, and stream iTunes to my iPad and then iPad will output the sound to the receiver via Bluetooth, but I have some 5.1 channel audio in library which I'd like to stream as well which is not supported by most adaptors.
i'm an Apple newbie and I don't know if AirPort would be the answer or not. In fact, I'm not even sure if 5.1 lossless audio can be streamed without losing too much quality or not.
Any tips, suggestions, or options would be very appreciated.
Thanks!
iTunes-OTHER, Windows 10
