audio/video async exactly the sencods of keyframes

[Schauerland]

I have a weird problem with OBS 29.x.x
sometimes (not every time) audio and video is out of sync exactly the time that I am using as keyframe intervall.

for example if my keyframe is 1 second, the audio (all track) are exactly 1 second out of sync.
if its 2, its 2 and I even testen 10 sencods.

It seems it mostly happens on very long recording sessions eg one or two hours or longer.

I've attached a logfile from my last recording session where this happend

No you don't, you have a configuration problem.

Remove the A-380.

Disable Game DVR & HAGS too.

I'm using A380 for AV1 encoding
I found the error. this happens if you change the audio sync in advanced audio to anything else then 0 ms
I've ajusted the audio sinc about 100ms.
In an older version it was necessary because audio timestamps did not work correctly.
Now this seems to be fixed in OBS 29.x
everything is fine now.
