Question / Help Mic and Cam (sometimes) not synchron

[Velios]

Hi there,

first of all, thanks for your guys`help the last days, sadly I got another matter: Sometimes mic and cam seem not to be synchron. Today I streamed World of Warships which was perfectly fine. Later on I streamed DayZ, which was extremly delayed (mid and sound output). Can anyone help me here?

I should add that I - as you can see - am using my headset mic for voice capturing.

*EDIT*

And that - when the problem appears - the WHOLE sound is outta sync, not only mic - webcam, as I just realized.
