I've been living with lip sync issues (audio behind the video) since I got my Playbar about a year ago but I finally decided to do something about it. After multiple conversations with Sonos support and the LG's support people (they kept blaming each other for the audio delay), I decided to email Sonos' CEO about the issue.

After a few hours, I got a reply back from him, CCing a team manager who was going to look into the issue. We scheduled a call and he had me send various diagnostics to him. He said that the engineering team was going to investigate and get back to me.

A week later, I got an update. He told that they are still working on the issue. He also said that only one other person had reported the same issue (I assume that means that only one other person with an LG TV). So, if you're having audio delay issues and you've tried all other troubleshooting, reach out to Sonos support and have them look into it. If it helps you might mention my reference number, which has already been escalated:

Keep in mind that my setup is pretty straight forward (LG C6 OLED TV connected directly to the Playbar via Optical, audio playing from the built-in apps) and every single thing LG and Sonos suggested, including going into the TV's service menu and changing things there.

I know there are multiple post on the topic so hopefully we can solve at least some of the issues causing audio delay.

Ronnieuk,

Most VMedia TiVo TV Channels are PCM stereo anyway... so surround sound is only really useful for channel 204 Netflix and the few HD Film channels.

Most of my testing is on my firestick on Netflix or prime. Only used the virgin box a little bit. It's a v5 box which has a Dolby output setting which I've enabled.

Even the suggested audio splitter will not resolve the Amazon fire-stick Apps delay issue, in the same way it does not resolve any TV in-built Apps.. so the only thing you can do is either...

Speak to Panasonic support and see if they have any suggestions. The Sonos Beam is just a speaker and it can only play the audio when it receives it and the Panasonic is not delivering that quickly enough through HDMI-ARC...
On some TV’s you may find the optical port will work a little quicker and so try switching the Beam to optical using the provided adapter. Obviously you will lose the HDMI-CEC control if you go down that route, but that’s relatively minor if it solves the lip-sync issue for DD 5.1 output.

Might email Panasonic but probably won't hear from them within the return window for the beam.

Not planning to buy a splitter as these things should work without needing extra hardware but I appreciate that it's worked for others.

If I did get a splitter then surely connecting the firestick to that instead of the TV would fix it.

Gonna do some more testing tomorrow and will post back if I improve this.

I've got lipsync problems on my samsung q8
Tv with sonos beam and sky q with hdmi pluged in to hdmi arc on tv tried all settings new hdmi lead to no avail so I've ended up using a optical lead pluged directly in to sky q box and beam not ideal but aslong as only watching sky it works not happy after investing over £3000 in new technology and it doesn't work together

Fez.

So you've connected your sky box straight to the beam and now have no lip sync problems?

HI all

Just bought the beam. Got it set up on my Panasonic DX750B via ARC. I mainly use my 4K firestick for movies etc.

I am having lip sync problems when the TV is set output bitstream but totally fine with PCM. Has anyone fixed this issue without buying extra equipment as the beam is expensive enough.

I read on av forums that the only real difference between bitstream and PCM is where the processing is done. Like if you select bitstream on the TV then it is the TV that does the work but if you select PCM then the beam does the processing and the sound should be the same. Is this true?

I have a few days window to return the beam if necessary but it sounds good and I'd rather fix the stupid sync problems.

Thanks.

Now I had the same problem. I had 4 play three’s and recently got a connect amp. I looked more and more into having sound from my Panasonic tv to my speakers, so invested in a beam.

Now on the sound from my Sky Q going to my tv then to the beam via arc was spot on, on the normal setting. As soon as I switched to Dolby on Sky Q, I was getting delays via the hdmi arc on the tv, and also the optical output on the tv, yet from the optical from the sky to the beam was spot on.

Frustrated as I wanted control the beam, and also sound from PS4 and NAS, I kept looking into it and funny enough a customer where I worked suggested the tv wasn’t getting the sound quick enough from the sky to tv when set to Dolby, I only had £1 hdmi wires from pound shop, so I went out and spent £20 on two sets of wires, which said supported up to 4K video and Dolby, Dolby Atmos etc in sound, so used one cable to tv from sky, and other from tv arc to beam, and hey presto! No more sound delay.

Next time someone says all hdmi are the same, and your been ripped off for expensive ones, just try them and take them back if no change.

Check your hdmi wires and maybe test some 4K hdmi to see if it improves.

Just finished reading through the whole thread. Same lip sync issues here on a Panasonic VIERA TX-58DX902.

Sky in DD, Xbox one X both have issues, however the Apple TV 4k is the closest with hardly any lip sync sometimes? Will play ok with itune purchases, but can vary dramatically when using infuse.

Have opted to order the https://www.amazon.co.uk/dp/B076XV1LVS/ref=pe_3187911_185740111_TE_item as advised by NeilAngels above. Will let you know how I get on with it.

Prodan, have you heard anything further regarding your case? I have an LGOLEDB7A and am living with delay on a $2000.00 SONOS surround sound system and am quite frustrated.

Do you still have Patrick Spence’s email? I would like to send him an email as well. Spent over $4000.00 on a TV and Audio experience that is frustrating me on a daily basis. I think we all deserve answers at this point.
