I have PHILIPS 65OLED804/12 65" Smart 4K Ultra HD HDR OLED and just got the ARC. Connected to HDMI ARC and it works great however there is a slight delay - sound is delayed. Every option is to delay it further. Any help much appreciated. 
 

only way around it is to change the audio to stereo on TV ….

      I have exactly the same TV with also the Sonos Arc and also these problems. The sound is too late. Very annoying. I hope there's a solution.

      The delay is caused by processing in the TV before it sends the audio out via the HDMI ARC. Check to see if there are updates to the software running the TV. Call the TV manufacturer. Sonos plays the sound as fast as it is handed the sound.

        I'm having a similar problem through my LG C8. Its not on every channel or recorded show but is consistent watching The Blacklist and The Flash. There is also a delay watching DA through my xbox one s. Thinking of going back to a Samsung soundbar.

        Sonos should investigate this problem

          I've read the DA app has been a problem for other soundbars when input is through the tv. I don't know if Sonos can help. The lip sync is just a touch out.

            I also have a lip sync issue with my Sonos Arc paired with Samsung Q9 75". Iv been trying to figure it out for a couple days now and I'm about to return it. I never had this issue with my Sonos Playbar.

            I also thought my xbox one s decoded dts to dolby on the fly. I think it only does it through optical. The lip sync is minor and only really shows with slow dialogue or something fast, such as a clap.

            Anyway, I really like the sound and simplicity for a living room space and the tv apps have had a boost in quality without having to passthrough a soundbar. Plus i'm moving and plan to have a summerhouse with a basic home theatre. I will need a new tv so will buy the cheapest one with eArc for the living room. If its still an issue, i'll sell it. The resale will be good. In the meantime, i have signed up to Disney plus to watch all the dts blu-rays i have, which are a lot of the Marvel movies. 

            Still, you would expect not to have any issues (excluding xbox- thats an app issue....i think)

            I know it’s not Sonos’ problem.  But given the magnitude of just the number of people, including me, that report this on the Community boards, I really wish they could engage at a level that we the average consumer don’t have access to.  They must do extensive product testing.  I would love to know which brands of TV’s they are performing their tests on.  Certainly, current models, from Sony, Samsung, LG, and Visio I would hope.  I realize that it’s not possible to check every model.  But they must be using at least some current ones.
