A background rumble appears in a sound from microphone in Sound blaster Live.
Hello!
A background (about 50hz) rumble appears in a sound from microphone. Windows XP SP2. I tried two headsets (which surely are good). The rumble decreases if I touch the computer case. I checked the inside of the case, did not find any improper contacts. The sound card is Creative sound blaster live ct4830. I tried the latest Microsoft and Creative drivers. The Creative driver does not output sound from microphone to speakers at the same time, but only from a recording from the microphone. How to prevent the rumble? Best regards, Dima |

Make sure that your computers power cord is a three prong plug. There is
the possibility it's not being grounded through the socket, or power strip if you are using one of those. In that case try another outlet, and maybe plugging the computer in directly rather than through a power strip. There's also the possibility of things being grounded in more than one way, and then you'd be talking about "ground loops" which become a little more difficult to deal with. Stay away from those 3-prong to 2-prong adapters. Good luck. -- HTH, Curt Windows Support Center www.aumha.org Practically Nerded,... http://dundats.mvps.org/Index.htm "D" wrote in message ups.com... | Hello! | A background (about 50hz) rumble appears in a sound from microphone. | Windows XP SP2. | I tried two headsets (which surely are good).

Does your computer run on 60 hz power or 50 Hz power?
Do you mean HUM or BuZZ rather than rumble? Rumble to most of us is the sound that came from our turntables when spinning vinyl records. Buzz and Hum come from the power lines etc. peace dawg "D" wrote in message ups.com... Hello! A background (about 50hz) rumble appears in a sound from microphone. Windows XP SP2.

Where are you located? What's the line frequency where you live? If the "rumble" isn't hum, then it could be a mechanical resonance of the computer's case with one of the fans. One way to reduce this is to put adhesive pads on the metal case; they're usually sold for dampening rattles in cars. Peace, Paul |
