How can you stop all sounds in a CodeHS program?

To stop all sounds in a CodeHS program, the appropriate function is stopAllSounds(). This function is specifically designed to halt any audio that is currently playing, allowing for control over the sound output in a program. When you invoke stopAllSounds(), it immediately affects all sound instances, ensuring that the audio experience can be managed effectively within the application's context.

The other options suggest alternative sound control functions, but they do not serve the same purpose as stopAllSounds(). For instance, muteAllSounds() typically might be expected to silence sounds without stopping them, while pauseSounds() would only temporarily halt sounds, allowing them to resume later. endAllSounds() is not a standard function recognized in this context. These differences highlight why the use of stopAllSounds() is the correct choice for stopping all sounds effectively in CodeHS programming.
