Xbox One X -> (HDMI)-> Lg C9 -> (HDMI ARC)-> Hw-q70r. I'm having the same issue. Atmos or Dolby digital has a solid 1-2 second delay , but DTS has no delay.
Would love to get Dolby Digital/Atmos/True HD working for hdmi sources via ARC/EARC... Internal apps work just fine with no delay.
Dvdman, I am on the latest firmware revision (03.60.04) and still experience the issue. If you have a different firmware revision that has fixed it please let me know, but from what I’ve heard this issue is present on all LG OLED TVs. I don’t think this would be fixed unless LG specifically state the issue as being fixed in the firmware revision change log.

I own the Samsung HW-Q70R, and when I do
Xbox One X(MS Xbox) -- <HDMI>-- Samsung HW-Q70R, -- <HDMI>--- C9(LG TV)
I get NO Dolby audio delay. The issue only applies when I plug the xbox into the TV (Which I need for VRR support etc.) and use either ARC or EARC
Can you try the setup below and advise if the problem continues?
Xbox One X(MS Xbox) -- <HDMI>-- SL8YG(LG Sound Bar) -- <HDMI>--- C9(LG TV)
I'd be interested to know whether anyone with an eARC capable soundbar or AV receiver experiences this issue as well.

A new firmware came out 2 days ago to download onto a usb stick. I haven’t tried it yet, but hopefully it addresses this issue.
