Hi. I keep my stereo under my tv and as such am hoping to save buying an apple express on top of my apple tv. I have an ATV3 which is cabled directly to my plus net Technicolor 582n router which in turn is mains ethernet adapter connected to my iMac (2011) upstairs. I have been assured by Apple directly that the most recent ATV will stream music, similar to how the express operates, by using a the digital optical connector. Heres the catch; my stereo does NOT have this connector so i am using a digital optical male to 3.5mm audio cable in order to compensate for that. It doesn't work, is there an easy fix i am missing? A different alternative cable? Or do i need to bite the bullet and get a Express?
