I have exactly the same problem. Only HD Streams affected, SD content runs fine.
It appears some days ago, not directly after upgrading to the latest LibreElec, but some time later.
Maybe some caching problem?
Kind of "fixed" it by reducing the resolution (from something above 3000x) to 1920x1080.
Prehaps related to "upscaling"?

Check advice from here: https://wiki.libreelec.tv/configuration/4k-hdr#hdr
Using 1080p60 for GUI with 4k modes enabled is whitelist is recommended configuration. (You will get 4k resolution for video).
Running the GUI iat 4k is pointless (the skin texures are 1080p) and just makes kodi laggier.
Tonight I will install the latest LE build 10.0.2 and test is the audio delay has been resolved on my RPi4.
hi,
Clean install or update?

Will do an upgrade first. Downloading the new build now.

That's it! I change my resolution to 1920x1080 and enable hw acceleration again and all works fine now: audio and video are syncron again, also for video in high definition.
Perfect 
Updated to 10.0.2. Audio delay still there. 
Okay, so I updated to LE10.0.2 and played one movie. Which played fine except for the audio delay. Tried playing another one and the system just freezed up. Did a reboot. Same thing. Movies I could play before don't play. The output switches to 2160p and the cogwheel just keeps spinning into eternity... 😑
Hi,
Same here, audio delay with new installation.
My settings, 1080p60 for GUI, whitelist 1920p60/59.94/50/24/23.976...

GUI with 50Hz is enough.
It is only neccessary to set 60 Hz, 50 Hz and 23.98 Hz in whitelist.

No you should set them all. Videos can be encoded with 59.94fps and 24fps and not allowing them in whitelist will mean occasional frame drops.

Never seen a movie with 59.94 Hz ... 
It's strange that this happens, I use the same hardware, the same settings. with libreelec 9 this did not happen, it was from 10 onwards that I was never able to watch any type of video again without having to touch the áudio delay.

The NTSC standard is 29.97 interlaced frames per second, which when deinterlaced requires a framerate of 59.94Hz.
So in general live TV in America (and other countries) uses this, and so do many DVDs.
You can work around general audio delays via advancedsettings.xml:
Code: /storage/.kodi/userdata/advancedsettings.xml<advancedsettings> <video> <latency> <delay>+150</delay> </latency> </video> </advancedsettings>Restart kodi using command systemctl restart kodi
This worked. However, it doesn't answer the question as to why the delay is happening in the 1st place. Maybe I should do a clean install sometime soon.
Anyway, thanks for this.
