I have a Yamaha RX-V740 reciever and on the website it says that it has a DAC in it but all of the inputs are RCA cables and don't those run an analog signal?  Also there is a fiber optics input in the front but I thought that was for mostly video, correct me if I am wrong and sorry for the nooby question.

The fiber input on the front is probably a Toslink for audio. Pick up a cheap cable and hook it up to your computer.
