Are you using any plugins that are not registered?

Since you say the noise occurs on EACH RealTrack, that would seem to rule out the BIAB Program and point to your recording chain. I also think Mike is right, so turn up the gain. There is a very low volume digital hiss that music normally hides, but in your case perhaps it is being heard.
