Lip Sync Problems
Sigh. I wanna love Sonos. But lip sync is not working. Sonos imposes enough audio delay to annoy for TV use. Are there any work arounds?
My understanding is that Sonos is imposing some latency due to wifi use. I read in one place 30ms, which isn't bad, but I read another place 70ms. The thing is my TV is already adding some delay compensation to the audio to match audio to video processing delay, such that what you see from the TV and hear from the audio is pretty much in sync... Its assuming that any soundbar I might be using won't be adding any more delay. There is no way for me to turn that off on my TV that I have been able to find: Sony XBR-65X850B. If anyone knows a secret way to disable it on the TV, I'd love to try it.
Are there any other work around? If I put the sub and soundbar onto wired ethernet, will the latency on sonos be reduced?
I have heard I might need to get an HDMI switch that splits out the audio to optical before hitting the TV, and feed that to the SONOS. In theory the audio would then be early and I could use the Sonos to add delay back, however, the Sonos only appears to have like 5 delay settings for the audio, I'm not at all sure if that will be fine enough control to match the audio to the video.
This is very furstrating, I love the concept of Sonos for music throughout my house, but it does not really seem to be a very good solution for home theater due to this wifi latency being imposed. I wish Sonos would at least make the soundbar take the sound immediately when only the one zone is being used, and when no wifi is actually needed...so that lip sync would be matching at the very least for watching tv.
