I recently purchased the Yamaha RXV-671 receiver and I am new to the whole Home theater world. The receiver is connected to 5 Klipsch Architectural speakers and a Klipsch RPW-10 SubW. I Did the YPAO configuration as instructed in the manual and all speakers work fine. When I am watching HD content from Netflix or so, connected through a HDMI cable, no Sound Field setting (like Dolby ProLogic Movie, Dolby ProLogic Music, Hall in Vienna, Hall in Munich, etc) produces a theater effect. Hardly anything comes out of the Sub. Even the sound from the other speaker are kind of weak, with nothing at all from the rear speakers. But if I select 7ch stereo, every speaker works fine, which proves that all speakers are wired correctly and works well. But, I didn't setup all this to listen to music and watch movies in 7 ch stereo! I am not sure what audio setting to choose when I am watching a HD movie or listening to some music from my iPhone! Any help is very much appreciated!
