Just the lips, or every other audio part as well?
You could start by changing the audio offset value, and if necessary, save the setting for all videos.
I noticed it form the lips moving out of sync of the video. I didn't watch long enough to see if it happened in other sounds.
I have an Intel NUC6i3SYH with 8GB RAM and 120GB SSD. I'm having 3 issues with LibreElec 8.0.1:
1. Sometimes when powering off my NUC either through LibreElec's shutdown menu or from the power toggle function on my harmony remote, about 2 seconds later my NUC will turn back on. This issue happens often and it's after playing a video. This issue also happened on two other NUC's, the same model that I'm using now and a NUC5PPYH with an earlier version of LibreElec, and I ended up returning those NUC's to the store. I never had this issue when shutting down Linux properly when I had Linux installed on my NUC and as I understand LibreElec is Linux based.
2. I get artifacting when VAAP-VC1 hardware acceleration is enabled, so I must disable it as a workaround to stop the artifacting. Same thing happened with the previous two NUC's that I returned to the store with earlier version of LibreElec.
3. I ran into lip sync issues when playing video. I have my NUC connected directly to my TV and I'm using the TV speakers for audio ouput.
Issues 1 and 2 also happened with previous versions of LIbreElec. They also happened in OpenElec. I don't think anything is wrong with my hardware because as I mentioned, the other two NUC's, one being a different model, had the same issues with LibreElec.
