Hi,
correct me if im wrong but your HTS-S1300 is not 3D capable, in order for this to work, skip the HDMI pass thru and connect the 480 to the tv via HDMI and use either Optical or Coaxial digital cable from your 480 to your HTS-S1300 and turn volume down to 0 on the tv, you will get DD or DTS sound from the HTS through your speakers and picture handled via HDMI.
