Applicable Products and Categories of This Article

TV does not produce any audio when using an HDMI® connection.
Follow the steps below to troubleshoot this issue.
  1. Ensure the HDMI cable is securely connected to both the source device (set-top box, DVD player, or other device) and the TV.

    NOTE: If using a HDMI to DVI cable [FIG.1] or and HDMI-to-DVI adaptor, additional audio cables [FIG.2] will be required.

  2. Set the TV to the correct video input to receive the signal from the source device.

  3. Set the audio output setting of the source device to output a compatible audio signal.

    IMPORTANT:

    • If using a set-top box, go into the Audio Settings or Audio Coding section of the set-top box menu and select HDMI to pass the audio to the TV.
    • Earlier versions of set-top box firmware did not properly handle automatic HDMI connections. You may need an update to your set-top box firmware or a newer set-top box from your service provider.

    NOTES:

    • Instead of setting the audio output of the source device to Dolby Digital® or DTS sound, try setting it to output PCM or 2-channel audio.

    If assistance is needed to change the audio settings, consult the instruction manual or manufacturer of the source device. Instruction manuals for Sony products are available online in the Manuals section of the Sony Support Web site.

  4. If there is still no sound,  rest the Tv to the original factory settings
  5. If there is still no sound after resetting the TV, replace the HDMI cable.

If the issue is still unresolved, service may be required.
