Hi I bought my son a logic 3 surround souns 5.1 system for his xbox at christmas. Connected it all up as per instructions, the sound is good except that i had a constant clicking sound coming from the right rear speaker., I contacted the shop who exchanged the whole thing for me this week. I set up system No. 2. and guess what? Yes, i have the smae clicking sound in the same speaker. Anyone any ideas what might be happening?I have tried a different xbox, no good. tried using optic cable, no good. tried using coaxial, no good. even tried hooking up a playstation 2, but the same clicki click annoying click, in my right ear. any suggestions greatly appreciated.
