no sound on hdmi

[norrie66]

I have a  kd 55x8005c tv and when I connect an h96 max android box there is no sound.tried all HDMI sockets, changed HDMI cables, tried the box on 4 different makes of tv and all working fine and the firmware is also up to date.done a soft reset and factory reset but still no joy.

thing is when its plugged in to say HDMI 1 and I switch to HDMI 2 then back to HDMI 1 via the remote then the sound appears but if I change apps, say youtube to Netflix then the sound disappears again and the only way to get it back again is to switch between HDMI inputs via the remote

any suggestions would be greatly appreciated

Hi

I guess what remains is whether the issue happens on the same TV with any other external HDMI inputs? Can you change the audio format on the box? I'm starting to think it's a compatibility issue.
