I got a new SB audigy SE fitted and tried recording a vocal track today - even after doing all of the above muting/zeroing ,I still get a low "buzz".



That noise is almost certainly the mic or cable or both. I would try a different cable first. Make sure it's a proper shielded mic cable. Guitar pickups are known for picking up noise from a CRT monitor if you have one of those. I don't know if a mic will pick up noise from a CRT but try moving away from the monitor anyway. This doesn't sound like a PC/soundcard problem to me but you can also try plugging your PC into another power outlet just for laughs.
