Hi, I currently have an Xbox hooked up to my 5.1 digital amplifier, although I'm having to use an optical > coaxial converter as the output on the xbox is optical and the input on the amp is coaxial......now, although this set up seems to work, I have noticed that every now and then I'm getting a kind of static inteference through the speakers. After wiggling a few cables and using a bit of the old common sense, I've now come to the conclusion that it must be the converter that's the problem, as pulling out and reinserting either of the optical or coaxial cables from it seems to cure the static. Also, I have absolutely no problems with digital sound from my DVD player or sound from my Sky box so my amp isn't at fault. BTW both the optical and coaxial are Monster cables so they're not to blame I bought the Converter from Maplin for £15 and I fear that I may have bought a cheapo piece of generic cr@p, as on their website it doesn't even mention what brand or make it is... Can anyone shed any light on these converters? Are there any other branded types that I could try? /edit i've found the converter that I bought on another site and it's made by a company called, "Dayton Audio".
