So, picked up a new set of headphones for Skype and gaming for when everyone else is asleep, and was recommended to get a sound card with a headphone amplifier on it as well. Got the Asus Xonar DG, and as soon as I plugged it in started to get interference from the front panel mic. Any idea how to fix this? I've played around with all of the settings in the control center, its either switch it off entirely or have the problems, neither of which is ideal. Wasnt getting interference from the onboard, so I'm guessing poor grounding somewhere, all I know is I've got a headache from spending 4 hrs trying to fix it...
