Guide to troubleshooting the Sound issue on Sony TV

In short: To troubleshoot this issue, reset the audio settings first. Then, reboot the TV by unplugging it from the power outlet for 60 seconds. Once the TV has finished rebooting, the sound issue should be resolved now.

Step 1: When using a soundbar, audio transmitter, or AV receiver

Do the following things:

  • Scroll down to “speakers.”
  • Change it to “Audio system.
  • Again go back to the “settings/options” menu.
  • Select “Sound adjustment.
  • Choose “Advanced settings.
  • Turn OFF the “Dolby Digital Plus Out

Now check if the sound coming out from the speaker. If not, go to the third step.

Step 2: Using Roku or Amazon Firestick

  • Go to the TV box menu.
  • Then go to settings.
  • From there, select Display & sounds.
  • Then select Audio and scroll to Dolby Digital Output.
  • Turn OFF “Dolby Digital Plus Out

Now you should be good to go.

Before you turn off “Dolby Digital Plus Out” or change any other settings, must power reboot the TV. Often a simple power reboot fixes this issue.

Step 3: Recovering audio settings to the default valueSony tv audio not working

If you don’t want to go through any hassle, resetting the audio settings might be the simplest choice for you.

Don’t worry! This will not remove any of the TV’s downloaded apps. Instead, this will just restore all the audio settings to their default values.

what I meant is, any customizations you made to the sound settings, will be erased and set back to their default values.

Here’s how:

  • Press the “menu” button on the remote
  • Select “Preferences” and then “Settings.”
  • Scroll down to “sound” and click “Reset the sound system.”
  • Select “OK.”

Once done, reboot the TV again. Now, check if the problem has been fixed. If not, you have one last option to try—updating the firmware.

Step 4: Performing a firmware upgrade

Sometimes the core file inside the TV gets infected by malicious viruses or malware. When this happens, the TV may start to misbehave, such as auto-restarting, displaying a distorted image, blinking red light, or even not turning on.

The only solution for this is either resetting the TV to the factory reset or updating the system firmware.

Typically, when Sony releases a new system update, the TV automatically catches it and upgrades its firmware itself.

But sometimes you need to check and update it manually. (If you turned off the auto-update option)

Here’s how to check for new updates:

  • Go to “Settings.”
  • Click on “Customer Support/Setup/Product Support.”
  • Select “Software Update.
  • Finally, press “Network.

If a software update is available, install it. Chances are that the audio issue on your Sony TV will be fixed after successfully installing the new version of the software.

Don’t power off your TV or unplug it from the power outlet during the update process. Interrupting the update process may cause your TV to become unresponsive or require repair.

  • Check the audio settings: Ensure the “Audio Sync” setting is turned on in the audio menu. This will help to correct any delays in the audio.

Q: Sony TV sound crackling

A creaking, crackling, or popping sound from your television is typical and does not indicate a problem. These sounds occur when parts of the room or your TV expand or contract slightly due to temperature changes. For example, you may hear the sound when you turn on or off your television.

Environmental changes, such as temperature or humidity, might cause the sound location to shift or become less detectable.
