so my issue is that on live channels audio is out of sync.
not all the time and not all the channels, but its a constant thing, whenever i go through the channels, i always bump into a few where theres a very slight, but noticeable sync issue and it definitely takes away from viewing pleasure.
this is happening on the 2nd gen. NOW Smart box (non-freeview version), but the same exact issue is happening on the newest roku ultra.
i played around with audio settings on the box (stereo, PCM, dolby, leveling, night mode, etc.) and also my telly, but nothing makes a difference.
by default this box outputs 50 HZ video, by changng display settings, i can go to 4K 60HZ, which also makes no difference to the audio issue.
i would also mention that other apps like BBC, ITV, ALL4 and others all work fine, and i never experienced this audio sync issue other than on NOW live channels (entertainment, cinema, sport).
also, this issue is not present on ON DEMAND content.
