There are many reasons why your Sony TV’s sound is not working. Common issues include a temporary system glitch, incorrect sound settings, or problems with the TV’s firmware.
Aside from these, loose audio cables or damaged internal sound processing unit/mainboard can also be responsible.

“I’ve had this Sony smart TV for a good 7 months now. Managed to snag it during a Black Friday sale. Gotta say, it’s been smooth sailing so far. But I’ve started to notice a little issue lately. Whenever I stream shows, sound randomly cuts out. Often there have no sound no matter how I increase the volume. I even tried using a soundbar, but it’s same. Any thoughts on what I should do? Why my Sony TV sound isn’t working?”—Harry, Texas
In this article, I will explain how to fix the problem if the volume on your Sony TV is not working or if you’re experiencing a situation where your Sony TV has a picture but there’s no sound.
Let’s dive in…
How To Fix Sony TV No Sound?
Here are the detailed step-by-step guidelines.
Step 1: If using a soundbar, audio transmitter, or AV receiver
[Skip this if you are not using a soundbar!]
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
- 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 cycle the TV.
Often a simple power reboot fixes this issue.
Tips: A less common but possible cause of no sound issue on Sony TV is Bluetooth interference. This can happen when you have multiple Bluetooth devices connected to your TV or nearby, such as headphones, speakers, controllers, keyboards, or phones. Simply turn off all the nearby Bluetooth device that is connected to your TV.
Step 3: Factory Reset the Sound Settings
If you don’t want to go through any hassle, resetting the audio settings might be the simplest choice for you.
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.
- 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: Upgrade the Firmware
Sometimes the core file inside the TV gets infected by malicious viruses or malware.
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.
