Headphone+ XMC-1 Help Please!

[badsarge]

I attempted to watch TV thru the XMC-1 yesterday. I plugged the mini cable connector directly into the female faceplate headphone slot on the XMC-1 and and the XPA-5 triggered OFF I get ZERO sound thru the headphones. . Scanned thru the XMC-1 owners manual and all I located was info on triggers. I unchecked the headphone trigger box and now the XPA-5 no longer powers down when the headphone cable is inserted. Great. I still get ZERO sound in the headphones. What have I failed to adjust?

Thanks to all !
