So I have a Sony 40" Television set with a Blu Ray player hooked through via HDMI cable, a VCR hooked through regular AV cables, and a PS2 hooked through with regular PS2 AV cables.... now the output on the TV was originally plugged into a little RCA AV selector box along with the my record player and sound from my PC (which only has on board sound- no sound card) everything played fine, except for when the computer sound was plugged in, it gave a massive feedback on every switch. Apparently it only will take the television audio, or the comp audio, without feedback.... So My G/F's parents gave us their old (!) technics receiver which I figured would fix the problem.... and even without the RCA selector box, I still have the same problem?!!!!! any help would be muchly appreciated
There is a loop somewhere.. most probably the line in on the pc to the line out .. try muting line in XD
