I have my apple tv 3 connected fine to my tv via Hdmi which works fine, however when connecting it to my home cinema system via digital optical cable I'm having trouble as there is no sound when I play my media, it only comes out through my tv speakers. Bought a Digital Optical Cable to connect my apple tv 3 to my home cinema system thinking my home cinema had a optical cable link, but it didn't. Then bought a digital optical cable to 3.5mm jack converter and that doesn't work. How do I connect my Apple Tv 3 to my home cinema? Cheers.
