I have an older Yamaha receiver (RX 596) that has no optical audio in, only traditional RCA inputs. I tried using a 3.5 mm mini audio to RCA adapter that would transfer my headphone output to the CD or AUX input on the receiver. Of course the audio was crap, lots of humming and low volume level. I also have a Canopus ADVC 110 digitizer. Can I input digital audio from the MP to the ADVC 110 with an optical to RCA converter, and then output the analog audio from the ADVC 110 with RCA cables to the RCA inputs on the Yamaha? Suggestions please for the easiest/cheapest way to get quality audio out of my MP and cleanly into my receiver.
