Hi, I have my PS3 connected via HDMI to my screen and via optical to my Sansui RZ4900AV. The problem is I get a high pitched noise to my centre speaker when the PS3 is on. It is not very loud but it is irritating. Any help will be appreciated. Thanks
I have the same problem with the RZ-4900AV, it manifests itself when any video application runs through either the optical or coaxial input. in my case it's definitely not the optical cable itself, which works fine on another receiver. optical or coaxial input of audio CD's is fine, but a DVD video on the same DVD player gives the high pitched whine. the same with the PS2 on the optical input, audio CD in the PS2 no problem, PS2 game or DVD video gives the whine... i think, unfortunately, it's a crap receiver... and i solved the problem by buying a RZ-6900AV, which works perfectly in exactly the same environment.
