Video and audio not sync

[Deadrick]

Hi all,
I realised there are video and audio timing sync issue with kodi player, using mx player wrapper for playback.

Using the himedia default player doesn't has much of sync problem. But because sometime I need 2 languages of subtitle which only mx player allows.

All my player are connected to a avr, which then output to the projector. I have a sony bluray player, which doesn't has sync issue when I use it streaming.

I recently just change to TV to projector and start to realise this issue, because the screen is bigger and make it noticeable?

I thought it was the projector but since Sony bluray player doesn't have this issue, and himedia default player seems to be better in the sync, but mx player is problematic.

Any solution?
