I got sky hd installed today and use my cambridge amp to give me 5.1 surround while watching sky movies etc.. However since i have had hd installed everytime i switch to an hd channel i get a kinda intreference sound, its fine switching between normal sd channels. The sky guy said it could be to do with the optical cable, it was a 3quid effort of ebay.
My question is do more expensive cables make a difference, i thought it was like a hdmi cable, digital signal thus no difference in quality? Anyone else had this problem, or can anyone offer a solution?
