First, be sure you are using the latest drivers and software update

Next, apply the recommandations of the following guide:

If you're using a laptop, try using it with the power supply plugged in (and not on battery).  I recently had audio glitching on a laptop that apparently has a power plan for battery operation that djuced didn't work well with.  Plugged the same laptop in, and this problem went away.
