Setup: Samsung UN40C6300, Pace RNG110 STB (Comcast), STR-DH510 receiver. Per Samsung's instructions for receiving 5.1 from cable, I have the RNG110 plugged into the receiver via HDMI, then HDMI out to the TV. DH510 is set to "AFD Auto."

There are several channels on the Comcast network that advertise themselves as "5.1", yet I never see the Dolby logo or the "C" (center) light up when viewing these [apparent] 5.1 programs via AFD Auto. I get the center when I choose other sound fields, but I don't necessarily want all that processing when I'm watching a show. I do want some dialogue thru the center speaker.


Either my setup (and understanding of features) is wrong or Comcast is not actually sending a full 5.1 signal to me. Can anyone shed some light on this?


Thanks.


Edit: Comcast confirmed that they are indeed sending me a 5.1 signal and my STB is passing it thru. So, I guess it's something on the receiver that I'm not getting.

Found my answer. from the rng110 manual:


Audio Output Mode has three possible settings:

Auto (provides the audio format best suited to the connected equipment)

LPCM (provides PCM audio only)

Pass (maintains the original incoming-audio format)


"Auto" is the default. I changed it to "Pass" and I'm getting 5.1 on AFD Auto.


Comcast was clueless on this.
