    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.

    Follow these steps to troubleshoot the issue:

    Note: The subwoofer is a speaker for playing bass sounds. Sound from the subwoofer may be hard to hear when the input source has less bass sound.

    1. On the remote control, press the + (Plus) button of the SW (subwoofer volume) to turn up the subwoofer volume.
      Note: The button name varies depending on the model (subwoofer volume, BASS, etc.).

    2. If Night mode is set to ON, set it to OFF.
      Note: For details regarding Night mode, refer to the product manual.

    3. Try to play the test tone or built-in demo music to verify if any sound is coming out of the subwoofer:
