I just purchased the 5000 along with an X940E last week for my new house! The layout of the family room is definitely not optimal - TV has to be mounted between built-ins over a fireplace and angled down, sound bar consequently has to sit on the mantle below the TV, one side wall has several windows, the other side wall has a door and a wet bar, the rear wall is only half height as it is open to a higher split level. A sound bar was a necessary compromise because it would be prohibitively difficult to wire for 7.1 speakers in the ceiling or walls, but this is still a step up from our last house where there simply was no way to have anything other than TV speakers in the room! I'm definitely happy with the overall sound quality, but there doesn't seem to be much of an Atmos effect - I definitely don't expect to have much if any surround sensation given the room and it being a sound bar, of course. I'm not sure if there's any sort of math I can try to do to tweak the seating distance/ceiling height settings to bounce the Atmos sound to the actual seating position better, at the moment I have it set for the real numbers. This means the ceiling height is set from the mantle to the ceiling, as the OSD suggests (ceiling is about 10.5' high, mantle is 5.5', so I set the height to 5'). The mantle height is also a few inches above ear level, but again, no helping that in this room layout. Any suggestions for a formula I could use to get the sound to the right spot? Or are there any Atmos demos that focus more on the upfiring speakers so I have a few minutes to walk around the room and figure out where the sound is arriving currently?
My other devices are an Xbox One S and an Xfinity Xi5 wireless cable box (also too prohibitive to wire ethernet or coax in this room, unfortunately). I originally had both devices connected to the TV and then feeding back audio via ARC to make life easier for wife and kids, but I noticed I had to connect the Xbox directly to the sound bar to be able to set the Xbox sound output to Atmos. It now properly displays Atmos on the sound bar LED, but I haven't tested with anything other than the demo videos on the Dolby app (pretty underwhelming, hopefully adjusting the distances in the soundbar settings will help). I wasn't having any issues with the cable box (not 4k/Atmos capable, trying to figure out if there's a 4k wireless box available because the wired 4k box does support Atmos), but my wife had some issues with pausing on demand shows and then audio being gone when they were resumed. So I've also connected that directly to the sound bar now, haven't tested to see if the on demand issue is gone but I did notice a few brief audio dropouts last night when watching a soccer game. Hoping that was just a feed issue or some quick censorship, though. Anyway, this has been a pretty helpful thread to read through over the last couple of days and see what I missed, looking forward to making a few more adjustments to maximize my experience!
