If you're experiencing audio delay issues, read this

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.

After many months on the Optical I tried the HDMI ARC port again.  Lo and behold, it’s not giving the audio delay.  I keep track of the firmware updates on the TV and maybe the the S2 update to Beam did something - no idea.  But here’s one odd thing, the audio was now slightly faster than the video.  Almost imperceptible.  So using the TV Sound/Expert settings, I added a slight delay.  

FYI: This is on a Samsung 2019 75” Q80R

 

The delay is BACK!!.    It appears the Xfinity box as a HDMI source is definitely worse than the in-TV apps, which is pratically perfect.  I also put a 18gbps HDMI cable on the Xfinity to TV connection and that didn’t seem to help.  I did try a high-speed HDMI cable with Ethernet for the HDMI-ARC to Sonos.  It’s better than the Sonos included cable but still annoying.  I’ll be probably switching back to the Optical which at least does not pose that problem.

My Sonos Beam still has a lip-sync delay and i’m now considering an optical switch as many have said this solves the problem. 

 

How does this work exactly - i have searched you tube and can’t see anyone giving instructions to complete novices as to how to set this up. Have i got this right 

 

Tv’s Arc hdmi to the switch’s hdmi slot that says ‘out’ 

Optical adapter supplied by sonos into the slot that says toslink and then back into the beam.

 

Will that then get rid of the lip sync?

 

If i then put an amazon fire stick into one of the switchers hdmi ports would the sound play through that hdmi channel?

 

It all seems very confusing - i love the sound of sonos but the audio delays are maddening.

 

Any advice would be appreciated.

 

This is the switch that has been recommended.

Hi mate I'm in the same boat as you with the Firestick and a Panasonic TV.  Netflix works fine with stereo 2.0 but sound delay on Dolby settings for 5.1.  did you try the switch from Amazon?

The built in TV Netflix app seems to work ok.  But ide rather use the Firestick! So annoying!

It's absolutely disgusting hat between LG especially and Sonos that this hasn't been worked out. This is all very expensive equipment that people work hard to pay for, and you get two products which cant even get something so fundamental like Lip Sync right?

I keep checking for a class action lawsuit to be started against LG. Their frontline staff are absolutely useless and just knowingly make things up to get people off the phone. Don't underestimate their desire to wear everyone out until the issue just stops being talked about and we just forget we are using stereo on our TV's instead of Dolby.

As for Sonos, get with the last decade and put a darn HDMI Port on your Playbar and Playbase. HDMI ARC would have solved this whole issue.

I have two beams. Connected to both LG and Samsung TV’s. The sync issue is bad on both. Shocking for the money you pay.

I have been tinkering with settings for over a year and still having issues...I’m ready to try the audio extractor. I have an LG B7 OLED, Apple TV 4K and playbar. Obviously, I don’t want to lose 4K or HDR. What is everyone’s thoughts on this? 
 

OREI HDA-912 4K 60Hz 18G HDMI 2.0 Audio Converter Extractor - SPDIF + 3.5mm Output - HDCP 2.2 - Dolby Digital/DTS Passthrough CEC, HDR, Dolby Vision, HDR10 Support https://www.amazon.com/dp/B07BHYXVTY/ref=cm_sw_r_cp_tai_z.o5EbNVMWN4H
 

There is also a 4K Arc version as well, should I need that?  I was just thinking I’d run Apple TV to the extractor. HDMI from Extractor to TV and optical output from extractor to HDMI. 
 

Thoughts?

Do you have any addition source devices other than the ATV?  If so, you may want to find one with more HDMI inputs.  I bought a product from J-Tech that’s also a good brand. 

No - just the Apple TV. That said, the ARC version also has more inputs as well. Not sure if I need that or not...

I did some additional browsing of this Orei.  You may want to check their web site directly for other related products that I did not see on Amazon.  I’m not sure if they are new models with more features.  Please let me know how this goes, because I bought a Optical In (3) to Opital Out (1). (which uses the Optical to HDMI adapter for my Beam.  I am interested in knowing if what you considering will work and also pass the DD+, which the Optical does not.

Hi All,

 

I have a LGC7 OLed, Sky Q, ATV and a Sonos Beam. I had the much talked about lip sync issue when using sky Q. I fixed this by using an Optical switcher. I am interested in the new Sonos Arc sound bar and want to ask if anyone has had lip sync issues with it and Sky Q so far? I know I could use the HDMI / optical converter like I do for the beam but then I would lose Atmos. I would also use it with ATV and an xbox one X as well.

 

I assume that the C7 that has Arc but not eArc will output Atmos.

thanks for any advice

I did find switching the video mode to Gaming helped quite a bit. The less processing the screen has to due the less latency.

Hmmm, this has me rethinking my Sonos Arc preorder.  My second choice is the Sennheiser Ambeo, but those can develop a glaring problem over time (center channel becomes muffled for some reason).  It’s also around three times more expensive than the Sonos Arc.

 

Only reason I’m trying to replace my 3.1 system is I want Dolby Atmos when watching all this new Dolby Atmos content and I cannot add separate Atmos and rear speakers.

That is indeed what is usually recommended (you theoretically get a better audio signal since it goes directly to the speaker and is not passed through multiple sources). 

Nor would it be there if some TV manufacturers would pass through the audio without adding a delay to the signal. 

For instance, I have two Vizio TVs, and not an issue at all.

So then this issue wouldn’t be there if the Sonos Arc had multiple HDMI inputs like a regular soundbar / AV Receiver and I had all my sourced going through the Sonos Arc.

Possibly, yes. I’m guessing you’re stripping out the audio signal before it gets to the TV’s electronics. 

Badge

So I’m not having this issue with my LG CX and Marantz NR1510 because all of my sources are connected to the Marantz instead of directly to the TV?

Agreed. In every case with a solution, it has been the processing / delay caused by the TV. Bypassing the TV’s audio stream has resolved the issue, which certainly relieves any responsibility from Sonos. The challenge then shifts to the handling of data from smart apps in the TV. 

I’ve tested to unplug the beam, and by passing Bistream Dolby from the PS4, there is also a delay in the audio from the internal TV speaker. This means that the problem is the TV processing audio coming from HDMI sources causing the delay. So if there is a delay with the Beam, the Arc should also experience the same issue… I’ve read a lot about this and it seems that many TVs have trouble to pass audio from one HDMI source to another, inducing a delay.

I have a Marantz NR1510 AV Receiver and don’t experience any audio delay or audio sync issues.  What is it with these Sonos soundbars that cause these audio sync issues?

I briefly owned a Beam and returned it after having audio delay and not wanting to deal with optical switches, etc..  I currently have a Sonos Arc on pre-order and am hoping it doesn’t have the same audio sync issues as the Beam I tried.

Since the Sonos effectively plays the audio information handed to it as quickly as possible, it sure seems like the issue is upstream from the Sonos.

Hi, my turn to complain ahah. I have a Philips 43PUS7354 and a Sonos Beam which works perfectly while watching content from apps inside the TV (Kodi, Netflix, Amazon Prime Video...), but when I use a PS4, there is a delay in audio of something between 0,5 to 1 second, which is very annoying, specially in FPS. I’ve set my TV settings to “Multichannel” output and my PS4 to “Bitstream (Dolby)”. The sound is great with 5.1 output but with a delay. If I put the PS4 to “Linear PCM” and/or the TV to “Stereo”, then there is no delay, but it’s much less immersive… I tried pretty much every combination (HDMI or Optical), and if I connect directly the Beam in the Optical output of the PS4, I get 5.1 and no delay. So there’s definitely something in the processing by the TV that delays audio. 

I have an hypothesis : when the Beam is plugged into the PS4, the Beam tells “I want DD 5.1” so the PS4 decode the audio, encode it in the right format and passes it to the Beam. With a TV in the middle, the PS4 decode the audio, encode it to whichever format the TV accept (and it can accept a lot), which is then decoded by the TV and reencoded in DD 5.1 to be send to the Beam. The extra process could explain the delay, which could depend on the power of the TV. 

I could be totally wrong on this, but if it’s true, there is no viable solution, except asking Sonos to support to support more format (DTS, Dolby Digital Plus) or asking TV manufacturer to put an option to manually set the audio format the TV can accept through its HDMI ports.

Eesh

Have the sony x900f and experiencing noticeable lag with ARC and optical..

Currently have it setup via optical as I didn't want to lose one of the enhanced hdmi ports on the back of the TV.. Inbuilt apps work fine with the exception of Disney plus which only outputs stereo for some reason, but the sky satellite box and xbox (was aware of the xbox problem) have issues with the sound being after the video..

Am I correct in thinking that an optical switch would alleviate these issues, I guess the problem then is that optical won't carry dolby digital plus so you'd have to make sure each of your input devices have an audio setting to output just plain dolby digital correct? 

Still new to all this..

 

Edit : purchased the following from amazon and hoping it solves my issues:

Hi

I have the same issues on my Panasonic. I have connected all external sources to the Beam using optical via a switch and picture and sound are perfectly in sync. You have to make sure that all sources output DD 5.1 only.

Ah, understood. There are many people that want to point the finger at Sonos. While Sonos does have some limitations, this isn’t one of them. 

Yea, optical only travels one way, so the Sonos can’t communicate back up the line to tell the TV what to do. Probably why the system is called HDMI-CEC, and not Optical-CEC :)
