How do I get the sound to go on on my tv?

I’m trying to watch a movie on my basement tv, and I have absolutely everything on the right setting.
Its on Component 1, DVD, and the Dvd player is turned on. The volume is all the way up, and the speakers are turned on, yet there is no sound coming out of the speakers. Any tips/advice?

If it helps, here are pictures, the first one is the tv itself:

And this next one is one of the speakers ( with the baseball on top of it)
