Applicable Products and Categories of This Article

This article will help you troubleshoot issues related to connectivity between your Sony Sound Bar and Subwoofer, and situations where there is no sound coming from your Subwoofer.

Please go through the 6 steps below to try to solve your issue:

  1. Audio content
  2. Subwoofer - Sound Bar LINK
  3. Night Mode
  4. Subwoofer Volume
  5. Bluetooth Mode ("Transmitter" vs "Receiver")
  6. Reset

  1. Audio content

    Make sure that the audio content you are playing on your Sound Bar/Subwoofer contains Subwoofer information. For instance, music without low frequency sounds (typically bass lines and kicks) will trigger little or no output from the subwoofer.

  2. Subwoofer - Sound Bar LINK

    Confirm that the Wireless Connection between the Subwoofer and the Sound Bar (LINK) is correctly configured. If you're unsure, perform the link again.

    NOTE: Make sure your Sound Bar is connected to your TV with a HDMI cable, and that the TV's input is set to the HDMI port on which the Sound Bar is connected. You will need the TV screen to perform the Link procedure.

    NOTE
    : Also make sure there is no wireless signal interference between your Sound Bar and your Subwoofer (other nearby wireless networks, metallic objects, etc.)

  3. Night Mode

    Check if Night Mode is activated. Night Mode is designed for use at night when overall volume needs to be limited, and considerably reduces Subwoofer output.

    1. Press NIGHT on your Sound Bar remote control
      Night Mode button
    2. Press the button repeatedly to select the Night Mode setting, and set it to [Off]

  4. Subwoofer Volume

    According to the model you own, the volume level of the Subwoofer can be set independently from the volume of the Sound Bar. Make sure the Subwoofer's volume is high enough.

    1. Press SW (subwoofer volume) +/– on your Sound Bar remote control to adjust the volume of the subwoofer

  5. Bluetooth Mode ("Transmitter" vs "Receiver")

    You can enjoy content from a Bluetooth playback device on your Sound Bar/Subwoofer system, or listen to sound from this system on Bluetooth-compatible headphones or speakers.

    • [Receiver]: This system is in receiver mode, which enables it to receive and output audio from a Bluetooth playback device.
    • [Transmitter]: This system is in transmitter mode, which enables it to send audio content to Bluetooth compatible headphones or speakers. If you switch the input of the system, “BT TX” appears on the front panel display.
      IMPORTANT: While in Bluetooth [Transmitter] mode, the Subwoofer - Sound Bar LINK procedure cannot be performed.
    • [Off]: The Bluetooth function is turned off and you cannot select the [Bluetooth Audio] input.


    If you cannot hear sound from your system, or if you are unsure, please try setting the Bluetooth Mode to [Off].

  6. Reset

    If none of the previous steps solved your issue, try performing a device Reset, and perform the Subwoofer - Sound Bar LINK process again.


    NOTE: Make sure your Sound Bar is connected to your TV with a HDMI cable, and that the TV's input is set to the HDMI port on which the Sound Bar is connected. You will need the TV screen to perform the Reset and Link procedures. Reset procedure
