i have speakers CONNECTED to my pc it has a usb and aux if i make the volume higher with the tuning knob the static becomes louder its not a software issue cause even when i disable the speakers the noise still stays.
if i use the speakers on something else this problem does not occur.
even if i plug the usb in a usb connector in a outlet it doesnt occur.
if i put the aux in another device it doesnt happen either(so i would think the usbs give enough power)
so it only happends when both aux and usb are connected to my pc.
does anybody knows how this comes and how to fix it, i dont want to waste a outlet for the usb connection.Good day Brent,

From what you have said in your post the most likely cause of the noise is a noisy 5V rail on the computer. DEPENDING on the motherboard this could be the main power supply or one of the many power supplies on the motherboard itself. If it is the main power supply then it would be best if you REPLACED it, HIGH levels of noise can cause other problems other than the noise in the speakers.
Could you please post more DETAILS of the computer to confirm this diagnoses
