How do I stop random music and noise from speakers?

For about a week now I have been on my computer watching a video or something. All of a sudden out of nowhere I hear the sound from the video of the two twin babies talking or I hear music but even if I close all the open windows it keeps playing. I have read it might be Malware. I have downloaded Uniblue registry booster and malwarebytes to see if it will fix the problem. If you know what is causing it and how I can fix it I would really appreciate it. If I need a program just put a link in the description.
