I have recently bought a superceeded RSP 976 for a good price, the sound quality is excellent, it's running into my older RB 985 power amp. I have had a couple of problems though, when watching a DVD movie from my Toshiba using Coaxial imput, the sound just suddenly dropped out. Swiching back and forth between anologue and coaxial imputs the sound wouldn't return except for this high pitch digital static. I immediately turned the processor off fearing damage to my speakers, after 5 minutes in the off mode I turned it back on and everything worked OK. Then while watching Digital TV using optical imput the Processor emitted this high pitched digital static again again the only way to remedy this was by turning the 976 off. Any clues to what is causing this would be appreciated.
