Sonos / Xfinity Issue - Not getting 5.1

TV: LG 55LM7600
Sonos: Playbar + Sub + 2 Play Ones
Cable Box: Xfinity Xi5 (wireless box)

I'm not able to get 5.1 audio recognized in the Sonos app from my Xfinity box. When using the same HDMI port/cable, I'm able to get Dolby Digital 5.1 from my Xbox One. I've tried all the settings on my STB and TV and am still not able to get 5.1 with any program I try. Is this an issue with the cable box or is there something else I should try? I just don't understand why the Xbox One is capable of delivering 5.1 and my cable box is not.

@controlav So this worked! Orded a used version of that remote from Amazon and was able to access the Service menu based on the instructions in that link you provided. Thanks so much.

One thing I found weird was that I could run my cable box through my Xbox One and it would recognize it as Dolby Digital 5.1 (without accessing the service menu).

So the Xbox One must be delivering sound over HDMI in a different way than the Cable Box by itself and when I use the HDMI in, it somehow translates that sound when sending to the TV.
