4k audio
Why is the audio on the 4K channels coming through as two channel PCM when the audio on the non-4K channel for the same program is showing as Dolby digital?

What box is your Xfinity source? What device is handling your audio?

I believe the Xi6 started using Dolby MAT on 4K around the time of the Workd Cup with one of its audio output settings, either Auto or Expert, can't remember which. Try switching to the one you aren't using now to see if that makes a difference. My 4K boxes are XG1v4s and they don't use MAT on either setting.

In checking back, posts at AVS indicated that the Xi6 starting using MAT on the Auto setting while Expert continued to output DD+.

Hi there user_x1npns, thanks for taking the time to post here on the community forums! To potentially narrow down the cause of the issue, are you noticing this on any specific 4K channel, or does it seem to be occurring on every 4K channel?
