Ok, So I done some research and it seems common on these soundcards for the buzzing I have Taken the Xonar DSX 7.1 Sound card back and been refunded the money, I am now looking for another cheapish Sound card any suggestions I am back to using the USB Sound card now, the thing with the USB Soundcard is it sound clear but you can hear static/buzzing without and that is just testing by sound recorder. All I am happy with my onboard sound.. I just want my microphone to sound clearer.
