Hi guys   Wow, 177 or so posts in this thread alone, and this isn't even the only thread on this issue.    Update from me - I'm almost used to the routine now of going to Xfinity device settings and reselecting "Surround Sound", each and every time I turn on the tv.  Note the setting does "stick" but the output associated to the setting does not.  Reselecting the Surround setting resolves the issue temporarily.  Next time I watch tv, it's the same routine.   It's sad indeed, and completely unacceptable, that I have become used to this reality.   In addition, I notice a periodic loss of sound, just for a split second, and it happens several times during any one program.  This happens on all HD channels.  Admittedly a little outside the immediate topic of discussion for this thread, but yet another example of the absolutely woeful inability of Comcast to provide their customers with a sound experience that befits all the hype Comcast likes to laud us with where Xfinity is concerned.   Well, Happy New Year everyone - or not if you're trying to enjoy glorious Dolby Digital sound with your Xfinity programming today! ...

Hi Guys I have been quiet for a while but have been monitoring the discussion.  I promised waaay back (see top of thread) that I would let you know how things changed for me when I installed a new Denon receiver.    Of note, the receiver is also my HDMI switcher.  Every HD component I have goes through here, and then out to the tv, all via HDMI, including the X1 box.  Also, I am still using the X1 box with the "green light" around the power down button.   So....after setting up the Denon I thought it was Christmas all over again.  My problems appeared to be resolved.  I set the Audio output on the X1 to Surround, and it stayed that way, right up until my X1 got "upgraded" several weeks ago. As an aside, I actually do like the new interface a lot :-)  Anyways, since the upgrade I have to go back in and switch to Stereo output then back to Surround for the Denon to recognize the Dolby Digitial signal.  Once selected the audio setting is maintained while I have the Denon on.  When I have switched off before I toddle of to bed, and then I switch back on the next day, I have to go flip-flop the audio settings again on the X1.   So the upshot is, I get to listen in glorious Dolby Digitial, but I have to make the change on the X1 each and every time I turn on the Receiver.  I've already wasted a good chunk of my life talking with Comcast and prefer not to waste any more, so I can live with it as is.  It's one extra (but should be absolutely uneccessary) step when I switch on.   All the best figuring out your resolutions, some of you have far more complicated setups than I do.  Good luck!   Matt ...

Exactly, according to the receiver my X1 does not output Dolby Digital, period.  As mentioned before I'll report back if anything changes when I hook the new Denon up via HDMI instead of optical. ... View more

Mine isn't even a companion box.  I only have the one main box, and I can't change the audio setting on that! ... View more

Hey, appreciate the response.  My current home theater is an older model Denon, but has an Optical Digital Audio "In" port.   It would display "Dolby Diigital" when hooked up via the Optical port to my old Time Warner cable box, before I moved to a Comcast area.   I have hooked the Optical "Out" on the X1 box to the Optical "In" on the Denon and it only displays "Stereo".  Doesn't appear to be receiving multi-channel digital audio.   The new Denon equipment alluded to in my original post will be hooked up via HDMI only, so will report back once tested to see if anything has changed. ...
