5.1 audio issue
When using the my xfinity cable box, the X1v4, with my brand new denon audio receiver with HDMI, I do not get 5.1 audio completely. The sound that comes out of the front left and right speakers is so low you have to put your ear to the two front speakers (left and right) to hear it. The center channel works great and the subwoofer works good too. When I use the receiver with my Blu-ray player all speakers work great and the sound coming out of the front left and right speakers are awesome. The issue only happens when I use (watch from) the xfinity cable box. When I had my old Xfinity cable box that had a optical out with my old denon receiver the speakers worked great. I’ve already tried the settings on the cable box for the sound and changed it to expert as well as 5.1 audio and it does not help the problem at all. I am beyond frustrated with the issue to the point where I might be canceling Comcast and going with AT&T if I cannot resolve the issue. Any help would be greatly appreciated!

So I am lucky to have the legacy DVR and X1 connected to my Dolby Atmos 5.1.4 (front center, left right, Rear left Right and Height front left, right and rear height left and right plus sub). When this evening if I turn on channel 216 which is Showtime and Dexter is on. The legacy DVR shows in the guide Dolby Digital (DD) 5.1. BUT on the X1 BOX, the guide shows this show WITHOUT DD 5.1 and when listening to this on X1, it is at best, simple stereo but on the legacy DVR, it is correctly full surround sound 5.1.
I have tried X1 device settings in Sound with Dolby surround as well as EXPERT Mode out HDMI (which is how i connect for both the legacy DVR as well as the X1 box XG1V4-A)
I do not know why so much of the X1 channels are simple audio and not Dolby Digital surround sound either on the guide label and in fact with the actual listening. it is NIGHT AND DAY... the legacy DVR has a FAR MORE IMMERSIVE EXPERIENCE for the audio.
for this reason, I find that I need to KEEP the old DVR until Xfinity can resolve this issue.
