Question / Help Audio problem, fine video

Hey,

I'm trying to get my stream going. The video works fine but the audio however has some problem. Every three seconds or so there's a mini lag, a small stutter in the audio. This is only for a few fractions of a second but large enough to disturb any music playing. Hopefully someone here can help me out. Note that this problem isn't there if I stream using xsplit so I guess it has to do with something in OBS. During my tests I've had my microphone muted.

My specs are:
50 Mbit/10Mbit internet
Windows 7 x64
i5 2.9 ghz
R9 x280 gfx
4 gb ddr3 ram

I tried to attach the log using the bracket code option but it said my post contained more characters than allowed so I attached the log file instead.

Thanks in advance!
