I have a problem with audio, at the beginning of the video, it is synchronized, but as the time goes, the video goes slowly out of sync. I'm using the default settings.
You can see the sample here, here and here.
Hope to get a fix

Could you post a DxDiag report?

Here's my DxDiag report:

I have the same issue.
I think it doesn't occur on every game, but on Battlefield 4 it is almost on every my record which is very annoying :/

I'm attaching my DxDiag

I had the same problem and posted a thread about it here: http://forum.mirillis.com/viewtopic.php?f=36&t=30845

You guys wouldn't happen to be using USB headsets?

I don't use any usb headset.
I use Xonar DGX + Superlux HD669 (jack) + Zalman MIC-1 normally plugged into back of my sound card.

I don't know then. maybe you could try doing a recording with a less elaborate setup, like just a headset plugged in and see what results that yield

I've just tested that recording BF3 is fine.
Desync is only with BF4 so it looks like Action! doesn't support it properly.

I wonder if there is someone who can record let's say 5 minut of BF4 gameplay without any desync.

That's why I was wanted to see the results of the test I suggested above. I tried a recording using just a simple stereo headset with no microphone and the recording didn't have any sync issues.

I'm not sure what do you mean by 'simple stereo headset with no microphone' as Superlux HD669 is just a stereo (jack) headphone without a microphone...
I use separate microphone also plugged into jack.

I've tried different presets (hifi, home cinema, headphones) + surround/stereo in Battlefield 4 and I always have desync.
