    Okay, I've been running stereo sound out from my Soundblaster Audigy card to my hometheater system for some time now and was wanting to run a digital connection now. I know on the back of my soundcard there is a s/pdif digital output, but the only s/pdif cable I can find anywhere is the RCA jack size. My output is the size of a small headphone jack... (1/8" i belive)... Any way I was wondering if anybody knows of a site that I could pick up dongle or something that fits into that small hole? I know its not an optical toslink connector or the rca size digital coax, so what do I need to be looking for? Any help would be much appreciated.

    I think that this would fit, but I don't think that that would allow the digital signal to pass through. That would be for mono or stereo sound not dolby digital. But thanks for your help Danny.

    Oops, I posted a stereo 1/8th jack, and the soundblaster manual says it needs a mono jack. Thus you'd use the following:

    It'll work. The RCA version of SPDIF can use standard cables.

    So that connector plus a standard RCA cable and your in business? I take it you connect the other end to your digital coax in, on the reciever?

    Make sure that the "standard" cable is a 75-ohm VIDEO cable and not an audio one. This ensures that there is no impedance issues and that everything works all hunky-dory.

    Ok.. so 75ohm video cable, I was at radio shak and they only had one of these Coaxial RCA connector cables and it was 40$!!.. Is this cable basically like a TV Cable connection with some RCA connectors at each end? I'd just rather make one or try an audio cable before dishing out 40$ for one of these.. thanks

    No, they have 75-ohm video cables for MUCH less than that. Don't use an audio cable, chances are that it has an impedance of something other than 75-ohm. This means that it MIGHT work but there will be some changes to the signal and quite possibly to the sound.

    Yes, a 75-ohm video cable is ideal, but we're talking about a 1.5 Mbps signal which will be carried over a short distance of typically 3 to 6 feet. An audio cable likely won't lose enough to make a difference. Someone (it might have been someone on this forum) demonstrated AC3 decoded successfully without errors using alligator clips and a coathanger.
