    Do you perhaps know of a cheap online vendor that sells them? Or should I look for them at radioshack?

    You could always build them yourself - grab some shielded cable and some phono plugs. Its dead cheap, and tends to work pretty well at removing hums - I use it for long video runs to stop interference or colour bleaching.

    Wait, did I miss something? Build them myself? If I were to try and build sheilded cable myself, then why would I buy sheilded cable...forgive my ignorance

    He means buy shielded cable and solder the plug on yourself. If you do this, you can manke the cables as long as u need. Ignorance forgiven.

    Sorry - being dumb again! Mike got it right - get some shielded cable from a hifi or electronics store and solder a plug on the end - it should help to get rid of interference.

    ok I am still a bit confused - I was under the impression that sheilded cables are regular RCA cables with thicker isolation all the way down the wire, but it sounds to me like the sheilded difference is made at the ends of the wires, is this correct?

    Ok, a quick lesson in Shielded cable...

    Have you ever seen coaxial cable?? This is the stuff that connects your tv to your aerial (at least in the uk n e way...). It has a central core which has a little bit of plastic insulation round it. Then, there is an outer "shield". This shield is a wire mesh of little tiny strands of copper that run inside the insulation of the wire. This wire mesh or shield helps to protect the cable from interference from other sources such as rf and em radiation. As cars are a particularly noisy (electrical sense not audible) place, shielded cable is a good idea!

    Do a search on google for more info

    Cheers

    I also have this noise problem,and I'm using SB Live. The noise is starting only when Windows is booting,it means I hear noise only after 15-20 sec of boot,so it can't be grounding problem,I disabled everything that I don't use - mic,line in,but nothing helps...
