Reply to whats with the clicks?

just got my s4 today and so far I'm loving this little thing, but for some reason it keeps clicking and making weird noises. does the sound card just suck on these or is it just me?

also I'm running windows 7(64 bit) with 4 gigs of ram and a core2duo. I've been using traktor for about a year now and have never had this type of problem before.
