Distrubing electrical resonance sound
Posted: Wed Sep 20, 2006 12:13 pm
Hopefully someone understands the problem:
I´m using G4 MDD Dual 867 to make music and sounds with live 5.
From the sound output there comes small electrical noise like beezzzziong or buzzzzing. It does not matter/disturb in everyday use as listening iTunes music or watching DVD movies, but when working with audio, the tiny background noise grows enourmous.
As an example: If I´m making a soundtrack for shortfilm where should be totally silence but only the clock ticking on the wall. Now I have totally silence but only the clock tick-tacking on the wall and little group of electrical flys making bzzzzzzz or brrrrrrr.
The noise comes only from the output, which is bit consoling, that it does not go to soundtrack and what I have done can be listened with no disturbing extra noise in any other audiodevice.
But I like to get thing fixed. To describe more of a problem: While was doing troubleshooting I found out that the noise is related to everything that happends on the screen. When opening a new window there comes bit different bzzzz and when dragging a window another brzrzrzrzrz.
So it´s like I had a disney cartoon movie soundtrack for everything I do, if I move a mouse there is a sound for that, if scroll a window bit down there is sound for that as well. So, at the same time it´s amusing and funny, but still disturbing.
With my little exeperience in audio & electronics I would guess that it might be something like:
The earth connection of Graphic Processing Unit and (Built-in) Sound Card had somehow been mixed or too close or something and that causes the electrical resonance that creates a disturbing bzzzz noise.
But what to do to get thing fixed?
I would be very gratefull to get some advices to how to progres in the troubleshooting.
