Sound Issues

Hi everyone!

There is something wrong and I'm looking if there is one out there that have the same problem as I have with the software...

So when I start a track don't matter when, during my sets there are a stutter or lagg like for a 0,5 second and then the tracks plays as normal again. Don't matter wich track I play, it happens to all of them. This happens to me with the controller connected and unconnected. I have updated all of my systems and checked the rekordbox settings, my computer is above the recomended system requirement. I have tried everything that Pioneer have suggested and have not found any sollution yet! 

Someone out there that has come across this or have another sollution? Please help me!

Thanks in advance!
