Since I have changed my TV (40" -> 65" 4K), I note a desynchronization with the sound around 20 minutes after the beginning.
The speed playback is in 1.5x.
The sound is in advance compared with the video and the subtitles.
If I stop, and play again, sync is OK.
I tried using LavFilter, no change.
I don't think my hardware is the problem. I have an Intel i7-9700K, a GeForce GTX 1070, and 16 GB of RAM.
I already had this problem before I reinstall windows 10.
Videos are MKV in 1080 or 2160px.

All is OK with VLC or MPC-BE.
But they are not PotPlayer. I prefer using it.

So, if someone has the solution, it would be fantastic.

New discovery : this lost of synch comes only with True HD Atmos 7.1 flow of 4K videos.
With AC3 or DTS, 5.1 both, no problem.
It's OK for me because my sound system is in 5.1, and I manage Pot Player to choose automatically the 5.1 flow.
But if one day, I buy 2 others soundspeakers, I will be in trouble once again.

Always try the latest beta version (x32 only) before continuing a discussion here.
When you have a problem (Follow steps 1,2,3)
This is NOT official support though. It is my contribution to Potplayer.
