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.

In that case, assuming your Firestick is outputting DD 5.1 and not DD+ try to discover if your TV has ‘pass-through’ on its ports .. so that the Sony TV does not check, or try to transcode, the audio steam from your Firestick Apps. I use the Firestick 4K too with the LG C9 OLED TV and I can say that device is working okay here, albeit I’m using the Sonos Beam over HDMI-ARC, and the TV ports are set to pass-through.

You may find a pass-through option in your TV Settings too, or by speaking to Sony Support, but if they don’t support that feature on your TV and it’s in-built processor is not quick enough to handle the Firestick surround audio, then you may have to look at by-passing the Sony TV altogether, with an audio splitter/extractor, like the examples shown in the links below…

Yeah I’m using the Playbar via optical and I’ve tried everything. I don’t want to downgrade the audio to pcm because it nullifies spending this much money to have only stereo output. So maybe a switch with optical as well?

A switch, with an optical output, certainly would remove the delay that is being caused by the TV’s internal electronics.

Is there any you could recommend? I contacted monoprice but they dont have one that supports 4k signals.

Also, when connecting the siwtch is it best to connect it to the EARC HDMI input?

Airgetlam

No, sorry, I don’t have any personal experience with them. My Vizio doesn’t mess with the pass through signal. Just search on Amazon, there are dozens, you can choose based on which features you want, and once you know which brand/model you want, you can get it anywhere that has it. Amazon is a great place to do research, but sometimes not necessarily the place to purchase.

Which connection on the TV would depend on whether you’re using apps on the TV, and a switch that accepts an ARC signal to send out through the optical signal. But if you’re not, the an HDMI video signal is the same across all inputs.

Thank you so much for all of your help. I have a switch here at home I am going to try first prior to making a purchase to see if that helps solve the problem. Thank you all that responded and answered my questions. Stay safe out there!

Ok so I connected everything to the hdmi switch. Ran the optical cable from the switch to the play at and one hdmi to the television since the switch has all other cables running into it and I still have a bit of a delay. Do I need to turn off any audio processing on the tv or is that now pointless?

Airgetlam

That would be pointless, the sound is not being processed by the TV, it is being extracted by the switch and sent to the PLAYBAR before it reaches the TV.

You’re the first person who has reported that there is still a delay in this setup, can I ask what source you’re watching? Not what program, specifically, but what device is generating the signal being sent to the switch? Can you supply a link to which switch you’re using? Can you also confirm that the audio settings on this device, actually every device you have connected to the switch, is set to Dolby Digital only, and not any other codec?

I am using a firestick. The switch I’m using was purchased on monoprice.
