Reply to need help with Traktor pro 2 audio card setup

I am currently using the sound card off of my desktop speakers for my main as well as my presonus 44vsl for my cue. I have them both setup with asio4all but every 10 or 20 minutes the mains start to crackle and progressively gets harder to hear the song. for the time being, i just reset the sample rate to 44.1k to get the audio back to normal. normally the audio going to the presonus goes bad when i use VDJ and i would do the same to fix it. Does anyone else have this issues or would know how to solve it?
