If you've noticed that your TV broadcasts in another language, it might be a setting on your TV that was accidentally changed. You'll most likely hear the broadcast in Spanish if you watch a channel that offers Spanish audio.  Only a few programs broadcast Spanish audio, and when Spanish audio is unavailable, English audio is broadcast instead. Therefore, it may take you until you start a specific program to realize the setting has changed. So, if you find yourself listening to a program in a foreign language, it's likely that you've inadvertently changed your TV's language setting.
