Well, when a Sony TV has no sound, temporary system glitch, wrong sound settings, or issue with the TV’s firmware are typically the primary culprits.

Often, you can troubleshoot this issue just by power cycling the TV, but sometimes it requires some minor changes in the settings.

However, in this article, I will break down everything about why your Sony TV’s sound isn’t working and what you need to do exactly to get it working again.

Here we go! Let’s dive into it.

Why is Sony TV Sound Not Working?

reasons why sony tv has no sound

As I mentioned above, Incorrect sound configuration, malfunctioning speakers, or temporary system glitch are the primary reasons for sound issues on a Sony TV.

Aside from these, loose audio cords or damaged sound circuits in the motherboard can also be responsible.

However, your Sony TV doesn’t have sound because of:

  • Technical reasons such as faulty cables, incorrect audio output settings, or speaker damage.
  • Software issues like outdated TV firmware or incorrect audio codecs.
  • Environmental factors like power cuts or interference from other electronic devices.

How to Fix Sony TV no Sound?

  • If sound isn’t working on your Sony TV, first reset the audio settings from the settings menu.
  • Next, disconnect the TV from the power source completely.
  • Wait for 60 seconds.
  • During this time, press and hold the TV’s power button for about 15 seconds.
  • Once done, power the TV back on and test the results.


Here are the detailed step-by-step guidelines.

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

Do the following things:

  • Enter the “settings/options” menu using the remote.
  • 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

If you happen to be using a TV box or Cable box like Roku or Amazon Firestick, do the following things:

  • Go to the TV box menu.
  • Then go to settings.
  • From there, select Display & Sounds.
  • 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, TV often starts 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, 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.

Q: Why do I have sound on some channels but not others?

If you have sound on some channels but not others, it could be due to issues with the broadcast signal or the audio settings on your TV.

Q: My Sony TV has sound, but it’s crackling. What should I do?

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.
