Was told (Via AVS forum) that going into the settings and switching from HDMI to DD would force DD through the HDMI. Well, that doesn't work.
This is most likely because the cable box is using HDMI to verify with the TV what is appropriate - and the TV is probably telling it "I have only two speakers - please give my PCM stereo!" At that point, it will override everything else. As I suggested earlier in the week, that means the HDMI cable will never be fed a DD bitstream by the box under these circumstances.
Cable guy told me I had to route the optical from the box to the 970 directly, as does this post I found from someone quoting page 12 form my Samsung manual.....
I agree with the cable guy in this case - routing the audio signal through the TV as you were initially trying to do is a very problematic arrangement when dealing with multichannel audio of any sort. Going straight from cable box to the 970 is really the way to go.
