I recently got a new computer and i will be doing some music recording onto it but i have a problem when them into my computer. I run my guitar into a boss br 800 and then into the computer veer usb and use it as a audio interface, the monitors are plugged into the boss br 800. when i plug the usb cable into the computer i get a really annoying high pitched noise all the time whilst the boss is connected veer usb cable. this tells me that it is the computer or the cable that is making the noise. what i would like to know if if there is any way of eliminating this sound? would it be better if i got a sound card for my computer and plugged the monitors into that? if so what would be a good sound card to get ?
