No sound comes out of the subwoofer

    Subwoofers are designed to play low-frequency bass signals, so the sound may be harder to hear. To make sure the subwoofer outputs sound, try playing an audio source that will make it easy to confirm the bass sound, such as a movie. You can also test the subwoofer sound by test tone or built-in demo music. For details, refer to the article Sound from the Subwoofer is too low.


    • If no sound is output from the surround speaker for the HT-RT5, follow the steps below to troubleshoot the issue, which will also troubleshoot the subwoofer.
    • Features and steps may vary depending on your product, so refer to your operating manuals for details.

    Troubleshooting steps

    1. Ensure the subwoofer is plugged in and turned on.
      Note: If any LED indicator is lit or flashing, the power is ON.
    2. Press the + (subwoofer volume) button or BASS button on the remote control to turn up the volume from the subwoofer.
      Note: The button name varies depending on the model.
    3. Check the status of the subwoofer LED indicator:
      • When the LED lights up red after turning on the audio device, the connection (link) between the soundbar speaker and the subwoofer may not be complete. Set the link settings again.
        Note: You can find the link settings by searching the index by LINK, Secure Link, or Connect the Subwoofer Manually, etc. For details, refer to the Operating Instructions.
      • When the LED flashes (slowly) in green or orange and lights up in red after 10 seconds, move the subwoofer closer to the main unit. Place the subwoofer where there are no obstacles, such as furniture, walls, or metal objects, directly between the unit and the subwoofer.
        Note: The LED may flash slowly in green or orange for more than 10 seconds.
    4. Disconnect the subwoofer's AC power cord (mains lead) and reconnect it after one minute. After turning on the subwoofer, set the link settings between the soundbar speaker and the subwoofer again.
      Note: For how to set the link refer to the Operating Instructions.
    5. If the issue is still not resolved, reset the Sound Bar. After the reset, perform the Easy setup process and then set the link settings between the soundbar speaker and the subwoofer again.
