Random Music playing on laptop?

[b.chun]

It happened before and it happened again several times and it happened just a minute ago... AGAIN.
It's not just a random buzzing noise but music or sometimes I would hear some sort of commercials or people talking.

It plays even if there is no program running and it just comes from nowhere and i dont know where it is from at all.
Sometimes I go on FB or twitter and it just plays suddenly. First, I thought it was an ad but when I checked , no sign of ad at all.

It plays for a minute and just disappears. It plays different sorts of music and just simply random things. I'm tryin to figure things out so I hope you guys help me out with this one. Thanks ! )
