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)
I understand . Again what erks me is the GEEK guys FROM BEST BUY have been out to address this at least 4 times and none could fix the issue . Ya know there suppose to be the experts and also I assume work with sonos directly ? All I get is ,

( WELL WE CAN TAKE IT BACK OR CHANGE IT OUT OR TRY ANOTHER TV ) I'm also having issues with my right rear speaker cutting out , which by the way Best buy is installing a brand new Sonos system today to try and fix that and the delay . Not sure it will fix either ? Stay tuned .
Yea, I'm not a fan of the Geeks, or the salesmen at Best Buy. Even here in the silicon valley, they just aren't very knowledgeable. But then again, someone who would be working for relative minimum wage isn't someone I'm going to rely on for a lot of information.



I hope that you get one of the ones who isn't the standard, and can help figure things out.
Hi



We set our SAMSUNG KS8000 audio delay settings without a hitch when we first set up the SONOS sound system. All was well until the latest SONOS software update. We've been unable to get lip sync accurately matched. It's the same 'need a negative audio delay' issue that many people have. We have set Samsung TV audio delay to 0 and Sonos to 0. There is still a minimal delay and unfortunately I am one of those OCD type people that cannot unsee the delay and I fixate on it....so frustrating! We've noticed that there is a different delay from channel to channel and I can't watch some channels any more as it's infuriating.



Did anyone ever find a satisfactory solution?



Maybe either TV or Home theatre systems manufacturers should come up with an inline processing unit with large memory and storage that will accurately sync both video and audio before outputting through TV and speakers. Come on INNOVATORS, get developing to perfect your products.
The TV people don't care much about lip sync. The film industry dealt with it in the 1940's. I've been in the control room of a local TV station and pointed out the lip sync issue on their own monitors. Their reply was a blank stare indicating: "you are clueless, you just don't get it!". In some cases a video tape recorded on machine 'A' will result in lip sync issues when played on machine 'B'. This does not bother the TV guys. In general, I find that the movie channels have the best lip sync.



In a few cases I have noticed that connecting the TV directly to the cable box results in the picture being ahead of the audio. If this is your situation, other than swapping the cable box and hoping that there is improvement, you are stuck with bad lip sync that is baked in at the cable company or TV station. From comments I see on the SONOS community, it seems that TV lip sync is less of an issue in Europe.
RRG UPDATE , OK , So the Geek squad from Best Buy have installed a new Sonos system for me . I will say it did fix the issue with the right rear speaker cutting out but no help with the audio delay issue . Some Channels are worse that others but no channel is correct in sync . Also , now while listening to music from my I phone it decides to cut the songs off about 2/3 way thru and stop playing . Change song manually and starts playing again ?

All the folks with suggestions as to how to re-configure the system are much appreciated but the way I see it is , I've

had 4 different Geek squad techs come to try and correct this but non were able . I have to assume they know what they are doing and follow the Sonos guidelines . My feeling is this may not ever get resolved ? So many brands of TV's , updates , technology , Wi-Fi , wireless , Streaming , ect . Maybe Sonos will respond with something other than call our tech support because it hasn't helped me any . If anything changes I'll be the first to post it .
RRG UPDATE , HELLO ALL , OK SO HERE IS THE LATEST . AS PER SONOS I HAD BEST BUY INSTALL THE SWITCHER I POSTED EARLIER . DEFINITELY HELPED THE AUDIO DELAY SITUATION OVERALL . I DO HAVE A HAND FULL OF CHANNELS THAT STILL HAVE THE ISSUE BUT OVERALL CERTAINLY HELPED . I WOULD RECOMMEND TO ANYONE HAVING THIS ISSUE TO TRY IT . AS FOR RIGHT REAR SPEAKER ISSUE , THAT TOO HAS BEEN RESOLVED

WITH INSTALL OF NEW SONOS SYSTEM . I WILL ALSO SAY THIS, IT IS MY OPINION THAT IF YOUR SYSTEM IS NOT SUPPLIED WITH AT LEAST 50 MEG OF WIFI I THINK YOU WILL HAVE ISSUES . ( NO ONE TELLS YOU THAT ) I STARTED WITH ATT AND 1 MEG ( BEST I COULD GET IN MY AREA ) NOT ENOUGH , SWITCHED TO SPECTRUM 100 MEG , MUCH BETTER AND LESS DROPS . IN CLOSING I WILL SAY I AM PRETTY HAPPY WITH TH SYSTEM NOW , VERY UNFORTUNATE THOU HAVING TO GO THRU ALL THIS AN WASTE MY TIME , PLUS ADDED EXPENSE TO GET TO THIS POINT .

NOW ALL WE NEED ARE OUTDOOR SPEAKERS FROM SONOS !!!!
Ryan , Nothing sitting next to speakers and as I noted above the speaker issue seems to be corrected . What is not corrected is while playing music on my I Phone the system just cuts the songs off and stops , I can forward to the next song and it starts playing again . This happens at random and often . As for interference in general , my system is set up with Direct TV wireless and the receiver is by the TV and playbar as it should be . If that is a problem the Geek guys set it up that way .

Now as for adding another component to correct the audio issue , Guess i'll try that , interesting to me that no one from best buy has ever mentioned that or informed me I would need to do that when I bought the system .

Also it is not only LG TV'S that have this issue , Stay tuned .
Sonos says use an HDMI Switcher ,Ordering this today per best buy recommendation to correct audio issue , will be installed by Best Buy , Will let everyone know how it works out .

I had lip sync issues when using the optical output of my Philips TV, but only with 5.1 audio from films steamed from Apple TV - live TV, including 5.1 broadcasts, and recordings were fine. After trying several options, I've ended up with a One For All SV 1620 HDMI switch (http://www.oneforall.co.uk/accessories/signal-distribution/smart-hdmi-switch.html) and a Neet audio extractor (https://www.amazon.co.uk/dp/B00H8T1DJ8/ref=cm_sw_r_cp_api_2pnDybAD0D949) which sits between the TV and the switch and is then connected to the Playbar.



As long as all your devices support CEC the SV 1620 seamlessly switches between them (no UHD/4K support though). Other switches I tried either didn't auto-switch or did but also auto-powered off and sometimes didn't wake up.



Now I have no lip sync issues on any source (Humax Freeview box and Apple TV) and full 5.1 when it is available.
I have a Panasonic plasma TV and no issues with lip sync. My Apple TV and XBox go into an HDMI switch with optical output, as my TV doesn't pass 5.1 audio through from HDMI sources to the optical connection.
I also have a Samsung TV and was able to sync picture and audio perfectly using the Samsung's adjustment option, did not even have to touch the Sonos adjustment.
I'd assert that a delay of only 1 ms would be impossible to discern.



PLAYBAR's inherent latency is 30 ms. This is to allow sufficient network buffering for the satellites (SUB, surrounds) to maintain sync without problem.



If lip-sync is an issue, and the TV can't delay the picture relative to its optical out, the only way to recover some latency 'budget' is to bypass the TV with the audio. TVs tend to take around 100-150 ms to process the video.



For external sources (cable, DTT, PVR, DVD, etc) with a digital out this is usually straightforward. Delay can then be added back as required, either in the PLAYBAR itself or in a digital audio delay device. The latter can be combined with a digital audio switch; google 'Felston' for example.
I use my Playbar with a 43" Visio TV in the bedroom and have no lip sync problems at all.
then I pressed the "skip forward 30 secs" button a bunch of times in rapid succession and then started playing it again. At that point the lip sync delay was dramatically worse within the very same program I was watching, I mean truly unacceptably bad - like those old dubbed kung fu movies.

Next time, turn the TV speakers back on and see if they're out of sync too. My suspicion is that the problem could be in the DVR.



is there any chance a poor/low home wifi signal in the part of my house where this is set up is contributing to the problem?


I don't see how it could.
I also have experienced increased lip sync when fast forwarding/ reversing and/or pausing my Satellite PVR (Humax). If it's a recorded program I stop and restart else if it's time shifted I have to live with it.



I use an HDMI switch that outputs the audio via optical connector to the Playbar and uses ARC from the TV when appropriate.



I have the feeling that this "issue" with changing lip sync only happened with the addition of this switch.
Thanks Ratty - I've already done that test. Sound comes out fine on the tv speakers in that scenario.
Thanks Stuart - if it makes you feel any better I don't think it's your switch. I'm having the same exact problem with the PLAYBAR plugged directly into the TV optical audio port.

One thing that's for sure is that sensitivity to lip sync is not the same in everybody. One man's tiny lip sync and hardly noticeable is a real annoyance to somebody else - Of course once noticed it's impossible to "unsee".
HighDrive,



If your cable box offers an optical output, as a test, connect this output to PLAYBAR.
I faced the lipsync issue and managed to sort it. It was basically due to me using the tv remote to increase sonos volume ( sonos provide the capability to use your tv remote to increase the playbar volume). After several trials and errors - playing with tv settings, sonos app settings etc.. what i did was just reduce the tv vol down to 0 using the tv remote which also brought the playbar vol to 0. i then used the sonos app to increase the playbar volume qnd voila the echo effect was gone!!! Phew!!
Hey HighDrive. I'm like you. I too have a lip sync problem that nothing seems to be able to fix. I, like you, have read every forum and tried every fix. Just wanted you to know there are others out here like you. What ended up happening? Did you return your system? Did you eventually learn to live with the delay? Did you....dare I suggest...fix your problem? (I know, unlikely, but maybe?).

With Love,

jlyons



P.s. I feel connected to you on a deep level because we share this. Hope you feel the same.
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 .




Would it not save so much headache just to use a switcher and take away any TV processing issues?

I'm the same. I've left it too late to return the sonos or the tv now though so I guess I'm stuck with out of sync audio.
Never had an issue on my samsungs
I think it's disappointing that Sonos don't support newer/better audio formats and that the only connection option is optical.



I have an old Denon AV Amp and a KEF 7.1 speaker system and I'm at the point at which an upgrade will be required once I decide to upgrade to 4K, as ALL decent AV gear now has HDMI switching and the latest HDCP and audio codec support.



Having such fantastic sounding speakers and then crippling them with a compressed optical input doesn't make any sense.



Sonos remind me of Apple in many ways, regarding what features they include with their speakers, except at least Apple are forward thinkers in terms of trying to predict features that will be commonplace within the coming years, whereas Sonos omit critical features/connections and keep outdated connectors such as SPDIF.



With the current AV offerings from Sonos I'll be forced to look elsewhere for an upgrade.
