    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.

    Select the symptom of your device and follow the steps to resolve the issue. Check your manual for model-specific information. Manuals are posted on your model support page.

    Note: If there is no sound coming from the wireless subwoofer or surround speaker, or the sound from the wireless subwoofer is low, refer to No sound comes out of the subwoofer, or the sound is low.

    No sound from the home theater system or home audio system

    Check the sound after completing each step.

    1. Disconnect the cables between your TV and the home theater system or home audio system, and then reconnect them.
      • Make sure the cables are secure at both ends.
    2. Verify whether your TV has an ARC label on the HDMI port.
      • If your TV has an ARC label:
        1. Connect one end of the HDMI® cable (sold separately) to the HDMI IN (ARC) port on your TV.
        2. Connect the other end to the TV OUT (ARC) port on your audio device.

          HDMI (ARC) connection

      • If your TV has no ARC label:
        1. Connect one end of the HDMI cable (sold separately) to any HDMI IN port on your TV.
        2. Connect the other end to the TV OUT (ARC) port on your audio device.
        3. Then, connect an optical audio cable from the TV's Optical digital audio out to OPTICAL IN on your audio device.

          HDMI connection

        • If you can't connect your TV and your audio device with an optical digital cable, use an audio cable instead.
        • For more details, refer to Connecting with a TV in the supplied Startup Guide of the home theater system or home audio system. Manuals are posted on your model support page.
    3. Verify that the audio output setting of your TV is set to audio system. Check your TV manual for more information.
    4. Turn off your audio device and wait for one minute, then turn it on again.
      • If the above solution doesn't work, turn off your TV and wait for one minute, then turn it on again.
    5. Make sure that Control for HDMI or BRAVIA Sync of your TV and audio device is set to ON.
    6. Make sure that the ARC feature of your audio device is set to ON or AUTO.
    7. Verify that sound is output from the TV after turning on the TV and then the audio device.
    8. Make sure that your audio device is set to TV input.
    9. Change the TV audio output setting to PCM and check whether sound is output.
      • If the audio device connected to the TV doesn't support compressed audio (such as MP3, ACC/HE-AAC, WMA9 Standard, or LPCM) the sound may not be output depending on the type of broadcast or video. Check your TV and audio device manual for more information.
