@HP29,
I understand you’re stating that your right speaker makes a noise, is that correct? I will try to help you with this issue.
Does using a set of headphones also make that noise, if you haven't tried that give it a shot.
Can you please provide the full make and model of the computer you have, If you are unsure where to locate that information have a look at this link for help if needed.
Please respond back at your earliest convenience.
Thanks
