Sound not Working on Sony TV (Working 5 ways to Fix)

There’s nothing worse than purchasing an expensive new TV and having it not work correctly. A common issue is that the sound on Sony TV does not work, or it continues to turn on itself, which isn’t a great experience if you’re watching your favorite show or movie and the volume suddenly cuts out.

Fortunately, there are several fixes you can try at home before calling in the professionals, so your television won’t be lying around useless while you wait to get it fixed by someone else. Here’s how to fix a Sony TV sound issue at home.

Why is the sound not working on Sony TV?

There are a few reasons why your Sony TV sound is not working. The first is that the audio input setting may be incorrect. The second is that there could be a hardware failure. The third is that the TV may be muted. The fourth is that the software could be corrupted. And the fifth is that there could be loose cables.

“So what to do when Sony TV has no sound?” Well, I will now give you some troubleshooting tips that you can use to fix the issue.

Fixing the Sony TV No Sound issue

To fix the Sony TV sound issue, check to ensure the volume is turned up on your TV. If the volume is not the issue, you may need to troubleshoot your TV’s audio settings. First, try turning off the Dolby Digital setting. This is often the cause of audio issues on Sony TVs. If none of them works, reset your TV to its factory settings.

I’ll go over all possible solutions in further depth below, including what you’ll need to do to fix your TV. Basic troubleshooting for each issue is also provided here, which may save you time. So, keep reading.

1. Check the TV’s audio and volume settings

If you can’t hear any audio coming from your TV, you should first check the volume to see if it’s muted. The volume could be turned down, or the mute button could be accidentally turned on. Actually, we often forget to check the basics. But maybe that’s the solution. So, ensure that the TV isn’t muted and the volume label isn’t set to zero.

You can also try resetting the audio settings on your television to see if it works. For example, if you have a Sony Bravia Smart TV, use these instructions to reset the audio settings.

  • On the remote, press the “menu” button.
  • Select “Preferences” from the drop-down menu and then “Settings.”
  • Scroll down to “sound” and click “Reset the sound system.”
  • Finally, select “OK.”

After doing this, if there is still no sound, move on to the next step.

2. Soft reset your TV

The second step to fixing the audio issue on your Sony TV is unplugging it from the power source and then replugging it.

Ridiculous! right? But it could be the most effective method of getting your TV back on. Wait at least one minute after unplugging. Before plugging it back in, be patient and, for about 30 seconds, continuously press the power button of your Sony TV. Ensure you’re pushing the power button on your TV rather than the remote!

This will help to drain any remaining power from the TV and allow it to soft reset. This isn’t the same as simply turning the remote on and off! After one minute, plug the TV back in, and you should start hearing the sound again. If it still doesn’t work, move on to the next step.

3. Check and change Dolby Settings

Another possible solution could be changing the Dolby setting on your TV. Dolby is a technology used in many TVs to improve sound quality. It is a system that uses a series of algorithms to process the sound and make it more transparent and natural.

Since you are experiencing audio issues on your Sony TV, checking and changing the Dolby settings is worth a try.

First, change the “Dolby Digital Plus” to “Dolby Digital.” For this go to Home > Settings > Display & Sound > Audio Output. Now set “Dolby Digital Plus” to “Dolby Digital.”

If you are using a streaming device like Roku or Amazon Firestick, go to the “Menu” and switch “HD-DOLBY” to “OFF.”

You can try changing Digital Audio Out to PCM if you have a Sony Bravia TV. To do this, press “Home” on your Sony remote and then go to Settings > Preferences > AV Setup > Digital Audio out. Now change this to “PCM.”

4. Update the TV’s firmware

Sony occasionally releases firmware updates. While these updates may not be mandatory, they can often provide essential benefits, like fixing software bugs, adding new features, and improving overall system performance.

Usually, your TV will automatically download the most recent version for you, but this does not always happen. Sometimes, you may need to check and update it manually. To check for new updates, follow these steps.

  • First, go to “Settings.”
  • Then click on “Customer Support/Setup/Product Support.”
  • Now select “Software Update.
  • Finally, press “Network.

If a software update is available, install it. I hope 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.

5. Factory reset Sony TV

Still reading? Very bad! If your problem remains, a factory reset may solve your problem. A factory reset will restore your Sony TV to its settings on the day you purchased it.

You can reset your Sony TV using the remote or without the remote. I will discuss those methods so that you can easily reset your TV if you still don’t have a remote.

☞ Using Remote

  • First, tap on your remote’s “HOME/MENU” button.
  • From the “MENU,” select “Settings.”
  • Then select “Storage and Reset.
  • Choose “Factory Data Reset
  • Finally, click on “Erase Everything.

Wait sometimes! Your TV will switch on and off several times before returning to the first setup screen. Now see if your problem is fixed or not!

☞ Without Remote

If you don’t have a remote control or you lost it, don’t worry! You can reset your Sony TV using the reset button. Generally, it may be on the right-hand side, the left-hand side, or the very bottom of the TV. Or even underneath! To factory reset your TV without a remote,

  • First, unplug your TV.
  • Press and hold the Power button and Volume Down at the same.
  • Keep holding these buttons and plug your TV back in.
  • Release the buttons once you see the Sony logo or green light on the front of the TV.

Depending on your TV model, this could take 2 to 30 seconds. If this method does not work the first time, you should try it again and again.


1. Nothing worked! What to do?

If your Sony TV still has no sound after you’ve completed all of the troubleshooting methods above, you should contact the Sony TV support team as soon as possible. You can reach them at 1239245-6354

If you need urgent help, Sony also offers a live chat service. For example, there may be an issue with the hardware of your Sony television in specific conditions. You can hire a skilled TV technician to resolve your problem if this is the case.

2. Why is my Sony TV sound out of sync?

There are a few reasons your Sony TV’s sound might be out of sync. It could be a problem with the audio, video, or even the HDMI cable. Try the following troubleshooting tips to get your sound back in sync.

✔ 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.

✔ Check the video settings: If the “Sync” setting is turned off in the video menu, the video and audio might not be in sync. Turn this setting on to fix the problem.

But If you’re using an HDMI cable to connect your TV to an external device, such as a Blu-ray player.

3. 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.
