I am fresh out of ideas. I have gone through the option menu and set the LFE to BOTH, in the BASS OUT menu (I have also tried the other 2 options) and yes the woofer is turned on, both on the actual unit itself and in the option menu on the receiver. I have tested the sub on another system and it works fine.
In the TEST mode all speakers hiss (as intended) and when it gets to the sub if you sit right next to it you can just barely hear it and feel air flow from the ports. I have tried volume control, both on the sub and in the menu. I can only hear the test noise when everything is turned up all the way... it is getting a signal from the receiver but it won't amplify it. Again the sub works on another receiver.

I feel that I have exhausted all troubleshooting options, and have only tearing the receiver open left. Please help...

RECEIVER: Yamaha HTR-5950
SUBWOOFER: Paradigm Cinema 10 (powered, 10")
