This is what I use on my older Onkyo AV receiver that also lacks HDMI, but has digital optical inputs.
Hey I have plugged my apple tv via RCA audio cords to my Sony receiver. Using AirPlay I am now able to basically use AirPlay to play music from my iPod and iPad over the stereo wirelessly. Cool I know, but know I am going to move my apple tv to my theater room. Is there any device out there that I can can now use to plug into my no wireless Sony all in one receiver (no hdmi) to pick up playnmusic from my android and iPod?
