I use virtual dj, but have begun trying to use 2 sound cards for two seperated decks into the mixer. My problem is one of them pops with what seams as the harddrive. At that time I was using the sound on the mother board, and a second sound blaster card. I noticed the popping was out of the onboard sound card, so purchased another sound blaster card. Now, no matter which two cards I use out of 3, one of them makes the popping sound. I can use anyone one of them by itself in single out mode and they all work fine. What's the deal? HELP!
