How to Fix Pluto TV No Sound? (Proven Solutions!)

Are you facing the Pluto TV no sound issue? We have plenty of ideas to fix it!

Pluto TV is amazing due to the wide range of free content you can watch, but it is pointless when no sound is heard.

That can happen due to hardware, software, or network limitations.

To solve the sound issue on your Pluto TV app, you will need to inspect many configurations and proceed with some simple steps, such as power cycling your TV and router.

Moreover, it might be necessary to update the app or the TV’s firmware. Let’s find out what is happening and how to fix it!

Pluto TV No Sound – 9 Working Solutions

Solution #1: Check Your Network

One of the first things you should do whenever the Pluto TV has no sound is check your network connection.

Perhaps the data is not being transmitted correctly; thus, only video is getting to your TV’s screen.

Do the following:

1. Restart the router;
2. If that doesn’t work, go to the TV’s network settings;
3. Check which network the TV is connected to;
4. Ensure that it is the router’s 5GHz frequency;
5. If that is already right, then clear the network data (delete it);
6. Add the network again.

When the issue is truly data-related, connecting to the 5GHz frequency should solve it because 5GHz is way faster than 2.4GHz.

Solution #2: Power Cycle Your TV

Is there no sound on Pluto TV? That might be due to a slight error in the TV’s hardware or software, which could be solved with a power cycle.

Some might think it silly, but such a step can do wonders.

Usually, it goes like this:

1. Turn the TV off;
2. Unplug it from the wall;
3. Wait a minute or two;
4. Plug it back in.

Some TVs, however, will refresh the hardware and system better if you unplug them while they are on.

It also might help if you press the power button (on the TV, not the remote) while the TV is off.

Note: Moreover, some errors might take a few power cycles to be solved.

Solution #3: Check Compatibility

Are you sure your TV model is compatible with the Pluto TV app?

For example, if you have a Samsung TV, it is only compatible with newer models that run on the Tizen OS.

Sometimes you might be able to install the app through apk or another non-official way.

In such a situation, glitches are expected.

Thus:

• Go to the Pluto TV site and look for specifications on which TV models and systems are supported officially;
• Don’t install Pluto TV as a third-party apk on your TV, as that risks installing viruses and glitched versions of the software;
• If your TV doesn’t have compatibility, you can try watching Pluto TV: from the web browser on the TV, using a Roku stick, via Chromecast, or with an HDMI cable plugged into your laptop.

Solution #4: Log In And Out Of The App

Since you can open the app, but only the audio doesn’t work, it is worth trying to log in and out.

When you do that, some of your account’s data will be deleted, which might also (hopefully) delete some of the corrupted data preventing correct audio processing.

Do this:

1. Open the app;
2. Find the profile/account details;
3. Log out of the app;
4. Go to Solution #5 to clear the app cache;
5. Open the app again;
6. Log into it with your account credentials.

It might be worth checking your email inbox for notifications by Pluto TV.

Your region may be suffering from data loss or inability to access Pluto TV’s full range.

Solution #5: Clear The App’s Cache

If you’ve had the app installed on your TV for a while, it has built up some cache data.

That helps the app to open quickly whenever you need it.

Still, the cache data can get corrupted and work backward, blocking some basic functions (such as audio).

Clearing the cache will help, so here goes a general guide for most TVs:

1. Press the remote’s Home button;
2. Go to the Settings;
3. Navigate to the Apps tab;
4. Click on “System apps“;
5. Locate the Pluto TV app;
6. Check its options;
7. Click on “clear cache“;

Note that your TV might not have the same options, so maybe you have to clear the TV’s entire cache (for all apps). 

How To Clear Roku Cache

Roku is one of the most popular TV systems, so we need to talk about it.

Here is how you can clear the cache on a Roku TV or Roku stick:

1. Click the Home button on the TV remote;
2. Move the cursor to the “Home” option on the TV;
3. Click the “Home” button five times in a row;
4. Click the “Up” button;
5. Click “Rewind” twice;
6. Click “Fast forward” twice.

Solution #6: Manage The App

It is also possible that your TV doesn’t have an option to clear the cache, whether individually or for all apps.

In that case, you could also try managing it by way of updating or uninstalling it.

Updating it should go like this:

1. Locate the Pluto TV app (on the apps tab or app store);
2. Check for its options;
3. Find a “Check for updates” button (or similar);
4. Install the software update if it is available.

Reinstall The App

We must also assume that an update is unavailable, but the app won’t have sound in any manner.

Thus, let’s try reinstalling it:

1. Locate the Pluto TV app;
2. Scroll through its options;
3. Choose to uninstall it;
4. Go to the TV’s app store;
5. Locate the Pluto TV app again;
6. Install it.

Solution #7: Check The TV’s Audio Settings

On the side of audio considerations, we must also consider the compatibility between the TV’s audio settings and the settings required by the Pluto TV app.

Most of the time, the single audio setting that makes apps soundless is the audio format:

1. Open the TV’s settings;
2. Go to the sound/audio settings;
3. Locate the audio format settings or “digital audio out“;
4. Set to “PCM” or “PCM-Stereo.”

Note: On any TV, the "PCM" audio format is the best for nearly everything you watch or play.

Solution #8: Examine Your Audio Output

Are you using an external audio device connected to your TV? A headphone, soundbar, subwoofer, speaker, etc.

In that case, configuring the audio output settings is the first step to hear anything.

Here is what you will do:

1. Go to your TV’s settings;
2. Locate the audio configurations;
3. Find the “audio output” option;
4. Adjust the audio output correctly.

If you are using Bluetooth headphones, you need to set it to “Bluetooth.”

If your speaker is connected via HDMI, choose “HDMI,” and so on.

Check The Connectivity

If the audio output is already correct, the problem might lie somewhere else.

Use some of these tips:

✅ When using Bluetooth, disconnect the device and then connect again to see if the audio issue is solved.

✅ If using a wired connection, you might want to ensure the cable is firmly attached to both ends.

✅ Also, check for rust on the cable’s ends and the ports on both devices.

✅ Try another cable with your external device or disconnect it and try a different device (perhaps the TV’s native speakers).

It is important to ensure which device is defective and whether only Pluto TV is causing issues.

Solution #9: Update The TV’s Firmware

If only the Pluto TV app is soundless on your TV, we will not suggest you reset the TV.

That would be too much work for something that is probably the app’s fault.

Rather, it is worth checking if your TV’s system has received a recent update. 

Do this:

1. Go to the TV’s settings;
2. Find an option such as “System,” “Support” or “General“;
3. There should be “Software update,” “System update,” or “Firmware update“;
4. Check if any update is available for your TV’s system;
5. Install it.

You might want to contact Pluto TV support if no update is available.

Quick Recap

Pluto TV no sound defeats the purpose of watching so many shows on the best TV screen.

In that situation, you will need to inspect some settings closely and determine the issue according to the instructions we have written above.

Your Pluto TV should work normally right now!
