Why does my Sony TV suddenly have no sound?
Your Sony TV suddenly doesn’t have any sound because it’s not set to its proper speaker setting. Another likely reason’s due to loose or faulty wires. Other reasons include an external device interference or a pressed “Mute” button. Lastly, it may be an audio setting that hinders sound from your TV.
Sony TV no sound: 11 fixes
#1: Press your remote’s “Mute” button
Well, here’s something you might’ve never heard:
Not all TVs display a “Mute” icon or message on your screen.
So, how do we address this?
Press the “Mute” or “Muting” button on your remote to make sure your Sony TV isn’t muted.
#2: Turn the volume up
“But my Sony TV doesn’t have any sound.
Why would this even be considered a fix?”
Because here’s what could be happening:
Your TV’s speakers might be damaged and still works.
However, there’s only an audible sound at higher volume settings.
This is a common case when your speakers are old or worn down.
To test the condition of your speakers, try turning up the volume to its max level.
If you don’t hear any audible sound at all, proceed to…
#3: Unplug all cables and external devices attached to your Sony TV
Put it this way.
If your external device has a built-in speaker, it might interfere with your TV’s speakers.
As a result, the device blocks any audio signal or sound that comes out of your TV.
In fact, this happened to my friend’s Sony Bravia.
After trying several fixes, nothing worked.
Instead, unplugging his PS4 USB cable from the TV’s port solved the sound issue.
Now, take note.
It’s worth considering all streaming devices plugged into your TV, such as:
In addition, make sure your headphones aren’t plugged in either.
Once you’ve unplugged all the devices from your Sony TV, restart it.
Then, after turning it back on, test your TV’s sound by launching any app.
Did it work?
If not, you might be dealing with a loose or worn-down wire.
#4: Inspect for any faulty wires
If you have a damaged wire connected to your TV’s audio port, how else can you hear any sound, right?
Occasionally, your cables and wires might be loose.
In effect, your TV can’t receive any audio signal.
“But how can I tell which wire or cable’s damaged?”
By unplugging all your wires and plugging 1 cable at a time.
That way, you’ll be able to check which cables need to be replaced.
Remember: Faulty wires don’t just affect your TV’s sound.
A defective HDMI cable’s enough to cause your Sony TV screen to flicker.
In addition, it can cause both display and audio issues on your Sony TV.
So, if you have any faulty cables or wires, you should replace them immediately.

#5: Set your TV’s audio system to “TV Speakers”
See – here’s the thing.
Every smart TV needs guidance.
Your remote is 1 way of proving that point.
And when it comes to your TV’s audio system…
If it’s not set to TV speakers, it doesn’t know where to play the audio or sound.
Think of it as if your TV’s lost in a maze.
Now, how do you bring it back?
By tuning your TV’s audio system to its correct setting:
- Press your Sony TV remote’s “Option” button.
- Tap on “Speakers.”
- You should see a pop-up menu appear on the bottom-left of your TV screen.
- Select “TV Speakers.”
#6: Change your volume offset to “Main” or “Stereo”
Your Sony TV’s volume offset allows you to adjust your sound levels individually.
But it’s also more than that.
This feature on your Sony TV adjusts your volume to a fixed level.
In effect, if your volume offset’s set to “Automatic,” you don’t have control of your TV’s audio.
On rare occasions, it might cause your TV to produce no sound at all.
But fortunately, there’s an easy fix for it:
- On your Sony TV home menu, go to your settings.
- Click on “Sound.”
- Scroll down and tap on “Volume Offset.”
- Select “Dual.”
- Tap either “Main” or “Stereo.”
- Test your TV if it has audible sound on both settings.
#7: Restart your Sony TV
You’ve come this far only to be greeted with a device restart.
Well, allow me to explain why.
First, we have to account for every possibility that’s causing your TV to produce no sound.
Second, any incorrect audio setting could also mean a software glitch or bug.
In effect, this causes issues like your Sony TV producing no sound or turning on by itself.
And what’s the best way to remove a software glitch or bug?
By restarting your device:
- Unplug your Sony TV.
- Wait for at least 3 minutes.
- Plug your Sony TV back into its power source.
#8: Set Digital Audio Out to PCM
PCM stands for Pulse-Code Modulation.
It’s a feature on Sony TVs designed for home theater systems or soundbars.
Put simply, if you have any of these devices plugged in, your audio setting should be set to PCM.
By default, your current audio setting might be set to “Auto.”
And if it is, this is 1 reason why you’re not hearing any sound coming out of your TV.
So, let’s fix that, shall we? Just:
- Press the “Home” button on your Sony TV remote.
- Select “Settings.”
- Click on “Preferences.”
- Scroll down and tap on “Setup.”
- Choose “AV Setup” (located under “LED Indicator”).
- Tap “Digital Audio Out.”
- Click on “PCM.”
#9: Reset your sound/audio settings
Remember that “1 astonishing fix I promised that would be worth your salt?”
This is it.
But how exactly does it work?
Right now, your TV isn’t producing any sound for several reasons:
- A software glitch or bug caused an incorrect audio/sound setting.
- There’s a cable that’s creating interference with your TV’s speakers.
- An external device plugged into your TV automatically changed the audio settings.
Now, you can tweak your Sony TV’s audio settings manually.
However, it also takes up a huge chunk of your time.
Not to mention, what happens if you accidentally set a wrong audio setting and…
Your current problem becomes worse than it already is?
That said, there’s a smarter way to go about this.
And it’s by resetting your audio/sound to its default setting:
- Press your Sony TV remote’s “Home” button.
- Tap “Settings.”
- Select “Preferences.”
- Click on “Sound.”
- Tap on “Reset.”
- Confirm the process by tapping “OK” on your screen.
- Launch an app to test if your TV’s producing sound.

“Wait – doesn’t that mean erasing all my TV’s data and files?”
Yes, but it’s not the only reason why it’s needed.
A factory reset is the most effective fix when nothing else works.
Or put simply, when your TV’s unresponsive to commands and countless solutions.
But before we start the factory reset, it’s worth noting that this process is different for:

#11: Contact Sony or your cable provider
So what do you do if your Sony TV still doesn’t produce any sound?
Your first option is to contact Sony.
Their operation hours are as follows:
- Monday to Friday: 9 a.m. to 9 p.m. ET.
- Saturday to Sunday: 10 a.m. to 8 p.m. ET.
At the same time, it’s also worth contacting your cable provider.
If you’ve recently installed any of the following:
They might be causing interference with your TV’s ports.
For example, your AV audio port might be causing a problem.
And what could be happening is only certain channels on your Sony TV don’t have any sound.
If that’s what’s happening to you right, your cable provider should be able to resolve this issue.
