hey!

ok, here's the problem. my monitors are humming only after my computer starts up windows xp. when it is still in the process of booting up windows it doesn't hum. when i'm using the monitors with a cd player it doesn't hum at all, so it's not the cables or monitors itself.

the intensity of the humming depends on the application i'm running, for example when i start firefox hums a bit louder.

i've got e-mu 0404 pci and behringer truth 2030A. i tried different sound cards and had the same result.

when i connect my headphones to the output of the audio interface it doesn't hum at all.

anyone else had a problem like this ?
wtf it's wrong ?

i have the same problem and i hate it. if the screen is white then its worse, also when connecting another external harddrive it gets terrible. i was recomended balanced cables but atm i dont have balanced outputs on my soundcard so whatever. im stuck.

exactly

i dont have the problem with the mac tho so probably a problem with weak powersupply in the computer i guess.

I get this too when certain webpages are open.

Doesnt bother me much though.

are you using the same audio interface on both mac and pc?

I was having the same problem however i have the same monitors just a different interface.

I am almost positive that it is due to the cables, so i went ahead and ordered some new cables recently, they should be here within the week im sure. When i get the cables i will definitely post my results here.

However are you using TRS cables or XLR, because i heard the 1/4" trs cables tend to be less durable over time.

noh on the mac im using the included (mac mini). on PC i use right now the internal on the motherboard but i had the same problem when using echo audiofire 2, the problem was even more prominent then(!). i use unbalanced TRS and i have a hard time keeping them away from the powerchords. i know it helps tho but i hope new cables and a new soundcard will help me more. if not i will have to get a better powersupply for my computer and i guess that aint easy to get any good help.

i had hum in my right speaker last week, had some other cables lying around so i replaced them and it fixed the problem.

use balanced jack to xlr cables, even if your sound out is unbalanced... Problem should be solved.

Also, if possible, have your speakers plugged in from a different household power circuit than the computer. Especially try to avoid having them on the same power strip.
