I imported tracks from my Tascam-DP-24 to Sonar X2 Studio.  And I also tired listening to the demo that comes with Sonar X2 Studio.  Every snare hit, for example, it is trailed by some kind of weird electronic sound.  When I listen to a file in iTunes, it sounds fine.   Any ideas on how to fix this? 
 
Also, if I can't fix this...  What USB interface would you recommend?  At this point in time, I'm mostly looking for a quality USB playback through headphones (more so than plugging in a mic for recording...I don't need that right now).  Maybe I have issues with soundcard compatibility and I want to try USB first.  I'm running Windows 8 and my computer has USB2 and USB3.
 
Thanks!
 

What soundcard?  How do you have it configured. Computer specs? Not enough info to hazard a guess.

I have an HP ENVY h8
AMD Six-Core FX-6102 Processor
10GB DDR3
1 TB HD (7200 rpm)
AMD Radeon HD7450 graphics Card 1GB DDR3
 
As for the sound card...I guess it doesn't have one...it's integrated:
 
IDT High Definition Audio CODEC
 
So...advice for a USB interface would be great.  I just need good play back!!
 
Thanks.
