When a band appears on a TV show and it is obvious they are lip synching, why do we not hear the drums that are on stage?

Question

What I mean by that is, obviously the guitars and other instruments are not plugged in, but the drums don’t have that option. So why can we not hear that the drums are actually live? Hopefully that makes sense what I am asking.
