I have spent 2-3 hours on Google and I cannot resolve this. Very frustrated. I have to delay audio 200-300ms to sync the audio, and even then I feel it goes out of sync as the movie goes on - but it could be in my head.
It does not seem to be specific to any AV formats, however most of my movies are 24fps. I enabled and disabled audio pass through and it didn’t do anything.
My setup:
HP xw8400PC(server)
Pioneer VSX-823 (AVR)
Odroid C2 (Client)
LG webOS 2.0 Smart TV
