I just purchased a Pioneer VSX-820-K and connected it to my Motorola cable PVR. The signal from the PVR is Dolby Digital 5.1 but the Pioneer is only putting sound out of the left and right speakers. There is nothing coming from the center, subwoofer, or surround speakers. Why is this and how do I get it to use the full 5.1 setup? I have tried monkeying with settings and can't get it to work. I even tried using both the coaxial and optical digital connections.
I know the PVR outputs a Dolby Digital 5.1 signal as my previous receiver had a graphical display that showed all 5.1 channels lit up meaning it was receiving a signal for them all.
I know the speakers are set up correctly as when I go in to the setup program on the Pioneer the test tones come out of all 5.1 speakers. Also, if I use my media player to output a DTS 5.1 signal then it uses all 5.1 speakers. It only seems to be the Dolby Digital 5.1 from the PVR that it will only use the stereo speakers.
Has anyone else had this issue or have any idea how I can fix it?
