Why can't I hear sound out of my TV speakers?

Vino wants to know if he can delete the apps on his Roku box. Leo says to click on the asterisk and select the app, and he can delete them from there.

Vino is also having issues with his home theatre system, and the TV speakers are going off when moving to outside speakers. Leo says that the TV thinks he has something connected, like a home theatre system, so it turns off the speakers on his TV. One option is to turn on ARC, or audio return channel. That will bring the sound back to his TV speakers while going to external sources. Connecting through an optical jack will also enable him to do it.
