24p and audio sync issues - Kodi Community Forum
https://forum.kodi.tv/showthread.php?tid=80247
djon, after finally getting XBMC up and running for a while, I have noticed that when switching to 23/24hz content, the audio plays slightly early when I have motion enhancer and cinemotion enabled. If I disable motion enhancer and cinemotion on my tv, and select both sync to video and sync to display via audio clock, then it seems synced.
69675 – audio broken in 24Hz/24p since 3.11 (regression)
https://bugs.freedesktop.org/show_bug.cgi?id=69675
IIRC it was the XBMC people that wanted the ntsc variants in the first place as their player defaults to sync to video exactly and would need to resample sound at 24Hz because of this (blu-ray are 24/1.001). Assuming you can reproduce the issue just using mplayer playing a CD - then I can't, maybe your receiver is just more fussy than my TV.

Xbmc has settings in it that are akin to reclock but these settings are user friendly and as simple as a few clicks in well based menu's that are not confusing. There are other settings that need tobe changed like audio speaker setup, 2.1,5.1 ect but i leave it for you to work out, it's in your xbmc system setting.
XBMC audio sync problems - Media players

The best option I've found so far is to turn off those options in XBMC and change the refresh rate in the NVIDIA control panel to 24hz, which seems ok so far but even then in some videos (mainly avi's) the audio still seems to drift very slightly out of sync sometimes.

Install XBMC / Kodi; Connect your PC to your TV using an HDMI cable; In your Graphic card driver change the refresh rate to 23 HZ or 24 HZ; Note: 23 or 24 HZ will be available only if your TV support it, most modern TV’s do. Since XBMC / Kodi version 13 you need to set “Settings level” to Expert in order to see all options
Yamaha A3010 1080p 24fps lip sync issues | AVForums

It could be that the video content for 24Hz is arriving at the HDMI output interface ahead of or behind the audio stream, whereas for the 60Hz content they're both arriving at the same time, more or less by coincidence. You might find that if you manually fix the lip sync for 24Hz content, it puts 60Hz content out of sync by the same adjustment!

What's on my mind: Choppy playback XBMC solved

Luckily the XBMC crew has solved this problem: you just have to know what options to turn on. Well here it comes: Go to "Settings" Go to "Video Settings" Go to "Playback" Turn ON both "Adjust display refresh rate to match video" and "Sync playback to display" Especially the first one is important: It sets your TV refresh rate to 24Hz.

If you can't run 24Hz go read about 3:2 Pulldown but i doubt it will be as good as on 24Hz screen. In KODI turn ON Sync Playback to Display(this will speed up or slow down video to match 24fps) and turn OFF Adjust Display Refresh Rate(it's not even working when turned ON btw) Turn off kodi with a top left button in the menu
