Yesterday we were working on a theater in a new home and ran into a problem with the two Integras we had in the equipment rack. I do not know the model number. We got the Apple TVs up and running just fine, audio and video working properly. The digital audio, however, would not work when coming from the cable boxes (Cox Countour boxes). We fed a tv strait from the boxes and audio worked fine, just not when run through the Integra. They're brand new out of the box. Firmware update did nothing to solve the problem, so temporarily we hooked up stereo analog audio just to get some sound through the speakers.

So, digital audio from the cable box to the integra produces no sound. Anybody got anything? Thanks.
