X1 audio is l/r stereo in 5.1 wrapper, no 5.1 audio

Did something change in X1 digital audio output? The XG1v4-A is outputting sound as stereo in a 5.1 wrapper, with only left and right channels available on many X1 channels and all app channels (like Prime, Peacock, Netflix, and AppleTV).  5.1 digital was available for most everything, but disappeared in early January. Have tried both auto and expert 5.1 audio modes and even multiple boxes but no luck. Frustrating to miss out on surround audio for movies, music and even the recent Olympic broadcasts.

That is a known issue, but only with stereo sources from third party apps in one of those audio settings.  (Don't remember if it's Auto Detect or Expert.)  I have two XG1v4 boxes and do not have that problem with regular channels on either of them.  I get DD+ 5.1 and Atmos on them.

Hey there, user_k6u6ul! Thanks for reaching out on our XFINITY Community forum with your X1 audio concerns. Our valued members must receive a seamless X1 audio experience and I am sorry to hear this has not been the case for you recently. As @BIslander mentioned, it is a known issue we are aware of at this time. How are the boxes working now after switching them out this weekend?

Thanks, but no change. Still plenty of issues for content/channels that should definitely be appearing w/5.1 digital audio.

user_k6u6ul, thanks for sharing. I understand your concerns and we are working on the fix. Usually, your recordings should be in the cloud. Are you able to sign into Xfinity Stream to see if your recordings are there?
