static noise on speakers

[reitze10]

hey 

i have a 5.1 philips speaker set up with a 3rd party skytronics amplifier. 

when i connect my speakers to my pc i get a static-crackling noise, and it gets worse when i move my mouse or type on my keyboard. 

if i connect my 3,5 mm jack to my phone it doesnt have that noise.

 

i tried using my frontpanel 3,5 mm but it doesnt show up in "sounds"

and the other 3,5 on the back doesnt make the noise go away either.

i think the problem is some noise between your amplifier and your pc, if i am not uncorrect your pc is connect too the wall socket that are grounded, and your amplifier is connected also too a wall socket but the plug too the amplifier is not grounded, i dont know if this is going too work just a opinion i am casting inn the air, if it is so, try too bound the chasis of the amplifer and your metal case on your computer or just the frame from your PSU but do this while the pluges are not connected too the wall socket, when you have done that, try and see if it worked, if it didnt work remove the cabel or bounding you did, i dont know for a fact that this is going too work, but it can work

Try connecting the amp to a different power loop in your house- if the noise is in the 50hz-60hz range you have a ground loop issue.
