I have a str 4300es and have the hiss. I only get the hiss when listening to blu-ray in high def sound(uncompressed ,true hd, and dts master audio) when I switch the soundtrack to dolby digital or dts the hiss goes away. I never hear it on my cable box or 2 channel stereo. It also seems to get louder and lower when switching the speaker pattern from 5.1 channel to 7.1,louder being the 5.1. I believe the receiver has trouble decoding the high def formats. Sony Tech Support says they have not been able to reproduce the hiss when they checked it out. I was curious if you tried this on your 4400es.
