I’m experiencing an audio delay on my Sonos Arc whenever I use native apps like Youtube and Netflix through my LG C9 TV. All the settings I’ve found deal with delaying the audio further, but none let you do the reverse (i.e. delay the video signal or pull the audio signal forward). It’s a delay of somewhere between 100 - 200ms using this a/v sync test video, and it’s just about noticeable to be infuriating: https://www.youtube.com/watch?v=TjAa0wOe5k4
This delay seems much shorter when I watch the video through my Shield device, but I’d like to stick to the native LG apps because of better Atmos support.
Any thoughts on why this might be happening and how to fix? I’ve looked at a couple of posts here and here but I don’t see a negative value for the audio delay on my TV sound settings. Here are my current settings:
C9 sound settings: Sound out set to HDMI ARC; Digital sound out set to Passthrough; e-ARC on; AV sync adjustment set to Off
Arc: TV dialog delay set to zero.
