Hi! I have a 5.1 reciever with digital inputs, and I don't really like the regular stereo quality of the 3.5 mm audio cable to RCA. I hear that there are cables that do exist such as http://www.ebay.com/itm/12FT-1M-Toslink-to-3-5mm-Mini-Plug-Digital-Optical-SPDIF-Audio-Cable-/190761170868?pt=US_Audio_Cables_Adapters&hash=item2c6a4077b4 And I'm just wondering if this would work for the iPhone 5. I've heard that it would work for a Macbook Pro. Thanks!
