I was going to try and connect my audio card (Chaintech AV710) to my old stereo instead of buying new speakers, since I have two pairs of stereo speakers. Unfortunately, the left speaker outputs (both main and remote) are dead. I've decided to buy a new receiver and would like to hook up the S/PDIF output from my AV710 to the receiver. The Yamaha receiver I was looking at has a digital input that looks a lot like the S/PDIF output, but does not use the S/PDIF term. Instead it says: "DIGITAL AUDIO OPTICAL jacks: For digital audio signals transmitted via optical digital audio cable. You can use the digital jacks to input PCM, Dolby Digital and DTS bitstreams....All digital inputs jacks are compatible with 96-kHz sampling digital signals." Will this work or will I have to use separate outputs from AV710 to the main and surround inputs on the receiver now (and subwoofer in the future)? Thanks for any and all comments.
