Using the TV in a home theater 
Your TV has several features that make it an ideal TV for a home theater. But you 
might not notice them because they remain in the background until you decide to use 
them. 
Turning off the speakers 
When you use your TV with a sound bar or an external amplifier and speakers, you’ll 
probably want to turn off the internal TV speakers.  
To turn off the TV’s built-in speakers, in the Home screen menu, navigate to 
Settings > Audio > TV speakers and change the setting. 
Tip: 
The TV’s internal speakers can be enabled and disabled automatically as needed 
by system audio control, as described in Enable system audio control. Using the 
headphone jack also turns off the internal speakers.
