This has been bugging me for a while, and after doing some digging online and coming up empty, I thought it would be a good time to turn to you guys for advice. I recently upgraded my home theater setup. It now consists of: 1 Onkyo HT-R500 5.1ch receiver (this will be the next thing to be upgraded) 2 Polk Audio Monitor 70 Floorstanding Loudspeakers (front left + right) 2 Polk Audio Monitor 40 Bookshelf Speakers (surround left + right) 1 Polk Audio CS2 Series II Center Channel Speaker 1 Polk Audio PSW Series PSW10 Black 10-inch Powered Subwoofer The quality of the sound is amazing. HOWEVER: Ever since I set it up, things sound... off. How? Well, it's mainly what sound is coming out of what speakers. I can tell that sound is coming out of each speaker, and doing a surround sound channel test on my recevier (you know, the one where it puts out a static sound out of each speaker in order, telling you which one you should be hearing) works fine! But when I'm playing a game, things which seem like they should either... a) only be coming out of the center channel or b) should be coming out of both front left and right channels ...come out of the center AND left speaker. For instance: Playing Mass Effect 3 on an Xbox 360, with audio coming into my receiver via Toslink Optical Audio. In-game, the main character's footsep sounds (which would make sense to either come out of both the front left and right, or just the center channel) come out of the center and front left channel, but NOT the front right. The same goes with dialogue. I know for the most part, dialogue should come strictly from the center channel. However, in my case, it comes out of the center channel AND the front left. Help me figure out what's wrong, guys. Is it that my front right channel isn't working correctly, and should be putting out the same sound that's going to the center and front left as well? Or is something else wonky, and the things I'm hearing out of the front left and center channels should ONLY be being heard through the center channel alone? Could this be a problem with my receiver? Prior to owning the Polk Audio speakers, I had a crappy Sony home-theater-in-a-box setup, but I never noticed any sound-direction issues (with things coming out of the wrong channels). I have tried physically swapping my front left and right channel speakers, but I get the same effect. I have double-checked the connections between my speakers and my receiver, and everything looks fine. This is driving me crazy. Help me out, guys!
