Speaker/subwoofer hum?

Asked by yannick (985 points ) February 20th, 2008

I am wondering if and how I might be able to stop the low hum coming from my computer 5.1 speakers. The hum can only be heard when no music is playing and the room is silent, however this is a problem as I need to keep the speakers on overnight (sounds loud when trying to sleep).

The hum only comes from the subwoofer, so I don’t think it is related to the quality of the speakers (or at least not entirely).

Are you wave levels all the way up in your sound options? Sometimes when they’re up all the way that will create a hum

1-Check the grounding on your system 2-Move other electrical devices away from your speaker(they may cause interference)

@ fallstand: the wave levels etc are all ok so that shouldnt be a problem. Ive also discovered that the hum still happens even when the speaker button is off. As long as the subwoofer is plugged in, it hums.

@gooch: that sounds like a good idea but I’m not sure how to check the grounding on my system… :P

many thanks guys…

Check grounding system.

Increase gain on computer and lower gain on speaker system.

Are the speaker cables close to power cords, power supply?
