ha ha i am also having the same sound card at home pc. one great thing abot that is if sound is not there sound will not be there. i mean here iam using creative soundblaster. but i can here that white noise if i increse the volume. especially when iam recording from stereo mix its clarity problem. but with my home pc with with realtek i cannot hear any background noise. but i think its just a matter of luck to get a noiseless soudcard even if it is same model
