Getting no atmos for Arsenal V Man U on my 4k firestick, normally I have no issues, 4k and HDR are working.
I did, i got atmos eventually but what i had to do was exit the stream to change channel then go back into the channel but then if i done this it caused issues after about 5 minutes where the screen would be showing stuttering really badly it looked like i was getting about 10 frames a second, if i exited the app then went back in and then i would not get atmos the first attempt but without atmos i had no stuttering issues.
