I have an old stero system that I was hoping to hook up my Apple TV directly to it using the optica audio output, so I bought the "Belkin 6' Digital Toslink Optical Audio Cable with Line-Out Adapter" from Apple.com http://store.apple.com/us/product/H7048ZM/A/belkin-6-digital-toslink-optical-audio-cable-with-line-out-adapter?fnode=1dcc00db7d7e5b351faa0a9af560b92922a013cb3bbf40d1c485840ad6c04fdaf377f598fc83a3cfdb3099faa5c297f374bf9ed51568fc53335cef4e832eecfcd88a63136c44f925ba7a755bb1c6564a29fc094f392b95662ce82f6916683147(which can be found here). I bought this in hoping I could use the 3.5mm attachment and plug that into my stero using a "RCA male to 3.5mm female" cable like this one: http://www.amazon.com/3-5mm-Stereo-Female-Y-Cable-6-Inch/dp/B000I23TTE/ref=sr_1_1?ie=UTF8&qid=1416211966&sr=8-1&keywords=3+5mm+audio+cable+to+rca So I plugged my optical audio into my Apple TV used the adapter on the other side and then plugged it into the female 3.5mm cord which was plugged in using the RCA (male) cables into the back of my stero receiver.... I got nothin... Tv is on and playing the music just fine... Everything is working except the stereo. Do I really need to buy a powered converter from optical to stero? Like the one shown here? http://www.gefen.com/kvm/gtv-digaud-2-aaud.jsp?prod_id=5279 Is there any other problems? Is there a setting I need to change within the Apple TV?... My receiver is old and has no special settings you just turn the knob to which input you want it to be playing from and it works Please help this should of worked, I honestly bought the Apple TV and cords for this one purpose, well and the fact that I didn't have a Apple TV in the living room yet. Please let me know if there's anything I did wrong, or something I forgot to do.
