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.

Instead, please check the following settings:

1. Center speaker features:
   • The sound from the TV speaker is created according to the built-in speaker configuration of the TV. The sound positioning tweeters or vibrating frame tweeters at the top of the TV screen reproduce high-frequency sounds from behind the picture. This allows the sound to precisely match what is on the screen for a truly immersive experience.
   • When connected to the S-CENTER SPEAKER IN​ port of the TV, the low- and mid-range sounds are output from the soundbar or home theater system, so you may be able to hear those sounds better than the higher-range sounds from the TV speakers.
2. Specifications and connection:
   • Confirm that the TV has an S-CENTER SPEAKER IN port that supports the Acoustic Center Sync feature.
     Hint: Not all BRAVIA TVs support the Acoustic Center Sync feature. For details, refer to the TV product website or the Acoustic Center Sync section in the following article: Which Sony audio products can use the exclusive features of BRAVIA TVs?
   • Make sure that the S-CENTER SPEAKER IN port of the TV and the S-CENTER OUT port of the soundbar are connected using the TV center speaker mode cable. For details, refer to the TV/soundbar operating manual or Help Guide.
   • Depending on the audio source, the sound will not be output from the TV.
3. Soundbar settings:
   • HT-A5000, HT-A3000
     • Press the SOUND FIELD button on the remote control, and then select Sound Field: Effect On.
       Note: If the output audio source is multi-channel, the sound will be output from the TV speakers even when Sound Field: Effect Off is selected. If the output audio source is 2-channel, the sound will not be output from the TV speakers even when Sound Field: Effect On is selected.

       Note: Depending on the input, audio signal, or sound field settings, sound may not be output from the TV, and some additional settings will be required.
