Problem with monitor speakers


New member
Hello guys,I have a problem with my speakers.I've noticed each of them sounds in different way (like a semitone lower and there are some frequencies lost maybe).I think the problem is inside the computer because it disappears if I connect the speakers to other devices (a phone).So I think the speakers and the cable are functioning,the problem must be in the pc.Do you have any idea how could i solve this problem?I made an explanatory video but cannot attach it.Thanks
