might not notice them because they remain in the background until you decide to use
them.
Turning off the TV speakers for home theater use
You can turn off the TV's built-in speakers if desired by changing the setting under
Settings > Audio > Speakers and change the setting. However, if you use an HDMI
ARC or eARC connection with CEC enabled, the TV automatically mutes its internal
speakers when it sends sound to an external device. It also mutes all sound when you
use the headphone jack on the TV, private listening through the Roku Enhanced
Remote Control or the Roku mobile app.
