I use to get a random popping noise when the 950 would switch between decoding functions. I never could find a way to remove this on my 5.1 SS system. The other day I decided to activate the other two speakers in the 950 setup for a 7.1 setup. I left them on, even though only 5 speakers are connected, and the popping has gone away. Thought I might see if others have had the same results.

Well I guess that proves once again that 7.1 is better than 5.1. Looks like you need two more speakers. I hope you can handle the hardship of having to buy more audio equipment.
