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.

    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?

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

    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.

    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.

      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).

        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.

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

        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?

        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

        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.
