ps3 problem or equipment problem?

[1lakerfan]

I have seen complaints on sound cutting off and causing speakers to make a poping niose. Ive experienced this frequently on two games and those are condemned (about once every minute or so) and in half life 2 from the orange box (continuous static type noise) and some other games just every once in a while. It also does this during the ps3 first loading up. I am connected through hdmi on a 7.1 setup with a reciever capable of uncompressed sound. (denon 2807) can this issue be fixed in the setting or can you recommned what settings the be.
