That's right, this only happens with mkv/h264 videos

For me only happens with some videos. Lot of avi's are out of sync. But most mkv's are in sync. So that throws that theory out of the window. But haven't tried build with updated ffmpeg.

I'm having the same issue but I'm probably using an older build than you are, still, the problem doesn't seem fixed in more recent builds as per your comments.

I don't know if you guys mentioned, but to, it seems to happen only when "adjust refresh rate" is turned on...

For me it's out of sync without adjust refresh rate. Only thing that is needed is 24hz to make it go out of sync with some videos.
You sure all your videos are in sync if you force xbmc to use 1920x1080 24hz video mode and then turn adjust refresh rate off?

If you are talking about setting the resolution inside XBMC, I can't do that because of this problem. But I did set the resolution and 24hz in Windows desktop and ran XBMC with those settings and "auto" on XBMC settings. It didn't seem to be out of sync at the time with "adjust refresh rate disabled".

i'm still having this problem with the final camelot build. I'm running Windows Vista, and it happens with most 24hz, 23.98hz movies including the sample uploaded here (http://trac.xbmc.org/ticket/5755). I've also tried downloading a nightly build from http://sshcs.com/xbmc/?mode=Builds , r 26336 but no luck. I have to set the audio delay to 250ms for the sound to be synced.

Anybody else still experiencing this?

I'm having the same problem for 23.976fps (23.98) and 24fps sources when setting the refresh rate to match.

This can be seen with almost all media players I think. A way around it would be to have audio delay set and stored for each refresh rate instead of the global audio delay that you can store as default now.

To manually adjust the delay as soon as you change refresh rate (source frame rate) brings the WAF down quite a bit.

The new WASAPI option fixed this for me.

I tried enabling WASAPI, but still having the same audio delay.

here is my debug log if it helps anyone: http://pastebin.com/f16b4d3db

Bump,

Nobody having this issue? It's really annoying, especially when playing 24hz, then 25hz movies cause i can't just set the default audio delay for all movies.

Did revision 26564 fixed this audio sync problem? Just wondering...

BTW That fix was removed on rev. 26641

Probably not since he decided to revert his change :/

I tried revision 26333, which should have that 'fix' included, but didn't help at all.

Also, I found a bug report at: http://trac.xbmc.org/ticket/5755 and it looks like a developer can reproduce it. So I hope it'll be sorted.

It's too bad that this bug is still here. I haven't had the time to try camelot yet but I had hoped it would be gone. As some previously said - it's definately bad for the WAF.
