The skipping happenned to me too and I found no way to correct it

For the soundcard you just have to go to Preference > Audio Setup > Output Routing.

With your soundcard you should have 4 channels so in Monitor put channel 3 and 4. In Master put channel 1 and 2.

Now plug your Speakers ( I assume they are your Master Output ) in the green plug and your headphones (Monitors) in the black plug (should be black, but it can be another colour ) in your soundcard.

You should be able to cue without hearing the monitor out your speakers.

Hope that helps!

not only the output setting, but in traktor there also is a control (in the middle mixing section, right below master volume) that contols the mix between master and cue in the headphones, meaning using that control you can set it to hear only the cue'd track, only the master, or any mix of the two in you headphones

Have you tried increasing latency? Also, is your computer powerful enough?
