Sound from the Subwoofer is too low.

    IMPORTANT: This article applies only to specific products and/or operating systems. Check the Applicable Products and Categories section of this article before starting these steps.

    What is the sound of the Subwoofer?

    Since a Subwoofer is designed to play bass sounds, when you play an audio source that has fewer low frequencies, the sound from the Subwoofer can be harder to hear. To make sure the Subwoofer outputs sound properly, try playing an audio source that will make it easy to confirm the bass sound, such as a movie.

    Make sure the Subwoofer is connected and turned on

    Make sure that the Subwoofer is properly connected to the Soundbar, and that the Subwoofer's indicator lights up.
