I am not totally sure??? My AVR-4400H is in the shop for repair, so I can't check. I actually have ATMOS (5.1.2), so my AVR is setup that way, the Xbox is setup to take advantage. On the games that support ATMOS, it works beautifully. On non ATMOS games it does upmixing pretty well.
Now, in your situation, only having 5.1
, and assuming you AVR is setup for only seeing 6 speakers, and the Xbox is setup to take advantage of those speakers, I think you are getting Dolby Digital Plus 5.1
for you. Or DTS-ES 5.1
/6.1, in 7.1 setup backs play as mono hence 6.1. or finally PCM, again depending how your Xbox is setup. All of this is dependent on what your picked to do your decoding... your xbox or the receiver.... but to my knowledge it will always be (Front Left), (Front Right), (Center), (Left Surround), (Right Surround), and SUB WOOFER.
I hope this helps.
