Hey guys, needed some help here. Im using my Firehawk FX to record some music for. I have it running into my computer with USB, and I'm using SONAR Artist as my DAW, if that makes a difference. I have two tracks, one for the left and one for the right coming from the Firehawk, and my output is also the Firehawk. It records fine without problems, but during playback it has this awful popping and crackling noise to it. Is there anyway I can fix this? Thank you in advanced.
