No sound comes out of the subwoofer

If no sound comes out of the subwoofer, follow these steps to troubleshoot the issue:

Notes:

• Since a Subwoofer is designed to play bass sounds when you play an audio source with fewer low frequencies, the sound from Subwoofer will be harder to hear. To make sure the Subwoofer outputs sound, try playing an audio source that can easily 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.

1. Check that the subwoofer is turned on.
   
   Note: If any LED indicator is lit or flashing, the power is ON.
2. On the remote control, press the + (subwoofer volume) button or BASS button 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 detailed information, refer to the operating instructions supplied with the product. Manuals are posted on your model support page.
   • 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 directly between the unit and the Subwoofer where there are no obstacles, such as furniture, walls, or metal objects.
     Make sure the router signal doesn't interfere with the main unit or speakers.
     
     Note: The LED may flash slowly in green or orange for more than 10 seconds.
4. Disconnect the AC power cord of the subwoofer 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 supplied with the product. Manuals are posted on your model support page.
5. If the issue is still not resolved, reset the Soundbar. After the reset, perform the Easy setup process and set the link settings between the Soundbar Speaker and the Subwoofer again.
