Please help!! I'm new to the HT setup, and have a receiver that doesn't appear to be working properly?? Just purchased an Onkyo TX-SR702 receiver, 4 Polk bookshelf speakers and center channel, and Velodyne subwoofer. Had HDTV, HD DirectTV Satelite receiver and DVD player working fine with the receiver. We were testing the setup by watching/listening to a few key scenes in some DVD's. We then did the "Automatic Speaker Setup" per the owner's manual. When we switched out of setup, there was only static (very loud static!). Now we can only get all the speakers to work through the DIRECT mode. All other modes produce static. Tried calling Onkyo... they're all out for the day due to inclement weather. Don't understand why it worked fine before the Auto Speaker Setup (done to try to improve the sound even more), and it's completely useless now. Tempted to return receiver if I can't get this working today. Any thoughts?
