A background rumble appears in a sound from microphone in Sound blaster Live.

They both hum from a headset microphone. Best regards, Dima |

Your card may not be up to the job. Creative bought E-mu as I remember, think about a 1212m, it has balanced line and the same converters used in the Pro Tools stuff. You probably will never be really happy with the card you have now. For currently $50.00 on E-bay you can get a 1212m, a daughter card will even give you time code. http://cgi.ebay.com/EMU-E-MU-1212M-P...QQcmdZViewItem |

Line in on the SB will be fine too. We're just fighting a lousy mic input and a selection of more-or-less lousy microphones. You can get away with lousy sometimes But not always. |

I have personally had this sort of problem quite a while back. It was
really bad if you moved the mouse. I found updating the mouse software fixed the problem. Also check if the IRQ that the sound card is using is being "shared", this can cause some problems also.

If no third ground contact, have an electrician remove the two contact
outlet and install a three contact outlet. Connect the ground to the metal box. "D" wrote in message ups.com...

If you have conduit, it probably is already grounded. Once a three contact
outlet is installed it can be tested by an outlet tester. Outlook testers are available at hardware stores and stores that sell electricians supplies.
