Laptop has been making a funny sound recently, all the way through?

I just looked at a few music videos on Youtube when my laptop suddenly hung up & instead of music, only such a long sound came. Have now several times turned off my laptop and turned off, but the sound remains. How can I cancel / deactivate this sound? I've just set the volume to zero so no sound, but I want videos again. Anyone have any idea what the problem is and how I turn off / off that annoying sound that's going on all the time can?

That's really little information for a remote diagnosis

But open the Task Manager and close all tasks in the background of those you do not know what they do! And do not worry the tasks you should not close because it tells you windows!

otherwise vll speaker defect or the like
