Hi guys, I've received a pair of QPAD QH-90 headphones for Christmas and have a bit of an issue with my sound. Whenever I plug them into my front port headphones I get horrible static sound from things such as the mouse moving around the screen, the disk drive working etc. There is just a non stop humming/buzzing sound when im not doing a thing. You can't notice this sound if music is playing just when it goes quiet. If i plug the headphones into my sound card at the back with the 'front' connector and put sound settings on Stereo I can get it to work without the noise, however I don't have the full range of sound then. My card is a Asus Xonar DG. I'm using the original front panel on an Antec 1200 case. The front panel is directly connected to the sound card, not the onboard sound. I have tried other headphones and the problem still persists.
