Incredibly frustrating. Trying to use Sonos PLAYBAR + SUB + 2 PLAY 1s for home theater. Have tried it on two different TVs (Samsung & Vizio) with HDMI inputted content (cable box & DVD player), also with internal apps native to each TV.



No matter what there's a millisecond delay between video lip flap and sound coming through the Sonos system. Before you ask, yes of course I've tried every possible way to adjust sound sync using both the settings within the Sonos app and also within the TV menus. I've read every Sonos forum post on it, and it's never conclusive and only offers suggestions to do what I've already tried. And believe me: I've tried it all.



Anyone? I had high hopes for Sonos because I can't run wires in my house to the particular area I need the surround speakers to be. Alas nothing's working and the only remaining to do is return the whole thing.



Disappointed! (Kevin Sorbo voice)
Lipsync drove me mad for many years, using 2 different TVs. All resolved now I've replaced the PLAYBAR with a proper AV receiver.
High drive, if you haven't figured this out I think I have it. I was experiencing this exact same problem. I needed to go to a negative number but there wasn't one. When fooling around with my cable options I took it off surround sound and bam, it worked. I actually have to now go to +200 to make it work, but it does. I hope this helps you. Again, from your cable options, make sure it's off surround sound and it should work.
I have non top issues with Sony TVs, I just picked up a Sony OLED and we have non stop issues with the Sonos. I plugged my cheap 99.99 sound bar in and perfect sync with the same optical cable. I have played with multiple settings on the Sonos and TV but still come out with issues. I even bought a HDMI audio extractor from the AppleTV to bypass the TV optical and that seems to help but I lose out on Dolby Vision and HDR. So not happy I decided to pick Sonos for my main HT watching..
Hate to sound like a broken record here but I have the same audio lag issue as well . Just had my brand new LG OLED55C

and brand new Sonos playbar 5.1 installed 2 weeks ago . Been working with Best Buy who installed it and a Tech at Sonos to try and resolve ? I hope they can fix this as I do really like the set up but the lag is very annoying . I'll let ya know the results .

Don’t LG TVs have an A/V Sync option on them?

We've been looking into some trouble with the newer LG OLED TVs outputting Dolby with lipsync issues. Some of them will have lip sync issues playing that audio content on the TVs built in speakers too, not just devices connected to the optical connection. Our team's currently investigating so if you'd like to work with one of our technicians to make sure this is what you're experiencing I'd suggest that you give us a call on our support line.

Ryan, is there a list of Sonos-approved TVs? I find myself sensitive to a/v sync and would like my next TV to be able to work well with my Playbase and support adjustment for a/v sync.
I'll chime in, I use my Sonos 5.1 with an HDMI switcher. I didn't notice any lip sync issues with Rogue One movie from Netflix played from the Apple TV last night. It sounded amazing, it was at half volume and my wife made me turn it down 😞. My daughter was entranced though.
RRG follow up . Spoke to Sonos tech , A couple times , he YES , in fact they do have an audio issue with LG TV's , others ?

They are working with me to correct this . Stay tuned .
