Hi guys just wondering what sound card i should be using for recording audio, I'm currently using a Neewer 3.5mm clip on mic as well as a pair of sanheiser 598 headphones plugged directly into a asus xonar dg sound card. Everytime i try to use both mic and headphones to work i get an annoying background/ white noise sound that gets louder the more i turn the sound up, Does anyone how any solutions to his problem. Thanks.
