Is your Xbox going through your TV before going to the receiver?
I've tried a bunch of other sources with Dolby and DTS audio and they all worked fine (no cut out). But as soon as I run something through the TV... the problem appears.
A thing that I did try that I haven't seen anyone else mention: switching the HDMI cable.
I started going through my collection of HDMI cables (about 6 in total) 2 of the other cables I tried did work at all when ARC was enabled (video was fine, but zero sound).
All my cables are +3 years old, so my assumption is that some of the older ones might just be HDMI 1.3 certified which would explain why there is no sound at all with some (ARC was introduced in HDMI 1.4).
As for the cable that DOES work, it's some generic cable that came with an HDMI switch (Olevia brand). So I'm guessing (more like hoping) that this Olevia cable has some funky stuff going on with in it.
So with that in mind, I ordered 2 new HDMI cables that explicitly say they are "HDMI 1.4 certified" as well as support ARC. They are in the mail and should have one by Friday and the other by Monday.
I'll keep you guys posted to see if that works
