How can I turn off sound from unidentified source coming on when I open the computer (Mac iOS)?

Posted

Starting yesterday when I turn on my computer, or after it has been in use for some hours, totally unexpectedly, unasked for, suddenly a commercial comes on, a speaking voice with background music - it can interrupt whatever is already going on, is not identified in any way, no accompanying images, and therefore of course how can I get rid of it?
