Re: 360 Audio out of sync - LG Atmos soundbar solution
After many hours of playing around I eventually figured a way to resolve a similar issue which may work for yourselves.
My problem occurred when I purchased an LG Atmos soundbar to go with my LG 4K TV. Disney/Netflix/Amazon apps that work from the TV were fine, no delays. However, when I connected my 4K Blu Ray player or Virgin V6 box I always had issues. The sound was delayed and my TV only had options to delay it further. No good! I tried different cables, optical connections, exchanging my soundbar for a new one and it made no difference. Here is how I resolved the audio sync issue:
1) On your virgin box, mine is the V6, goto settings and video settings.
2) Make sure the 'pass-through' video modes are enabled, mine were not, you may have to do some test first.
3) Now, on your TV, goto the sound/audio options, and if your using Optical/HDMI arc, you should have an option to select 'pass-through', don't leave it on PCM or Auto, select pass-through.
4) Sorted! 🙂
p.s. if like me, your Atmos sound tracks sound tinny, use an optical cable to force Disney/Netflix/Atmos/BluRays to play the dolby digital 5.1, optical cable only can process 5.1. You will lose the overhead speakers, but gain much deeper sound.
