Just hooked up my new Pioneer VSX-44 receiver to my TV, Uverser receiver, BD player etc. All works fine but I'm not getting sound to my powered Subwoofer (5-7 year old 10" Polk model). I've tried every possible combination of speaker set up (selecting "large" for the main speakers, then small, then PLUS for the subwoofer etc. Nothing works. Worked fine with my Onkyo last week. So not sure if its a defective unit (seems doubtful) or some setting somewhere. The CD has a 70 page instruction manner written in obtuse language. "making you better feeling" any suggestions would be appreciated.
