Hi, I am not able to get any sound through my Teac AG-D2000 receiver, when the cable box is connected through it using HDMI. So the connection is, my cable box is connected via HDMI to my Teac receiver into the HDMI DTV/CBL input. The HDMI monitor out connects to the TV. I don't get any sound through the speakers connected to the receiver. However, I do get sound through the TV, which I find strange. On the receiver I set the the input to Digital and that didn't help either. Any ideas on what I am missing?
