There's little or no sound from my TV speakers with my soundbar or home theater system connected to the S-CENTER port

    IMPORTANT: This article applies only to specific products and/or operating systems. Check Applicable Products and Categories for details.

    If you don't hear any sound from the TV speakers when connecting to a soundbar or home theater system using the S-CENTER port, this is not a malfunction of the TV or audio/video device.

    1. Center speaker features:

      The TV speaker sound is created according to the TV's built-in speaker configuration. The sound positioning tweeters or vibrating frame tweeters at the top of the TV screen handle the high-frequency components to create an optimum sound position behind the picture. This allows the sound to match what is on the screen precisely for a truly immersive experience.

      When connected to the S-CENTER SPEAKER IN port of the TV, the low and mid-range frequencies are output from the Soundbar or Home Theater System, so those sounds may be more pronounced than the higher-range sounds from the TV speakers.

    2. Specifications and connection:
      • Confirm that the TV has an S-CENTER SPEAKER IN port with the Acoustic Center Sync feature supported.
        Hints: Some BRAVIA™ TVs support the Acoustic Center Sync feature. For details, refer to the TV product website or the Acoustic Center Sync section in the article Which Sony audio products can use the exclusive features of BRAVIA TVs?
      • Make sure that the TV's S-CENTER SPEAKER IN port and the Soundbar's S-CENTER OUT port are connected using the TV center speaker mode cable. For details, refer to the operating manual or Help Guide.
      • Depending on the audio source, the sound will not be output from the TV.
    3. Soundbar settings:

        • Press the SOUND FIELD button on the remote control, and then select Sound Field: Effect On.
