If so that would be the problem try plugging it into the line in socket. If it is a microphone then make sure that it is being fully pushed home, if it is then try another one (they aren't exactly expesinve). Others have mentioned ground loops etc, but try the easy bit (normally the cheapest bits) first. As a matter of fact I get a continual low level 50hz hum from my line in post unless I actually plug something into it then it dissapears, so you could also try turning off all ports you are not using before doing your recording.
