Is there any way to get out the sound on my pc speaker
yes, but that makes no sense - you would definitely loose the ability to prelisten your tracks!
you would have to choose your onboard soundcard in traktors preferences and then you'll find only one output pair to assign...

and what is the function of the output preview,
if you use internal mixing mode and if you have an external soundcard (not an inbuilt like in the vms), you could assing one output pair to the preview deck in traktor. i think not many ppl are using this feature and like to prelisten their tracks more in the opposite decks as it was always the way in "traditional" DJing.

fx return.
some mixers provide send/return jacks, this is for using send/return effects. it's just another way of routing an signal and hence the processing is different. again, i assume, only a minority of DJs is using it (if their hardware provides it).
