Having issues with no sound on Pluto TV? This comprehensive guide covers 15 fixes to restore sound on your smart TV, streaming device, laptop and more when using the Pluto TV app.
Why Pluto TV Has No Sound – Common Causes
When Pluto TV suddenly loses sound or audio won’t play properly, it kills the viewing experience. But don’t panic yet – in most cases the issues can be easily resolved with a few troubleshooting steps.
Here are the most common reasons for Pluto TV no sound problems:
- Low volume or muted settings
- Incorrect audio configurations
- Loose HDMI/audio cables
- Internet connectivity issues
- Outdated/buggy Pluto TV app version
- Incompatible or glitchy device hardware/software
- External speakers not set as audio output
- Excessive app cache buildup
Understanding the potential sources of the problem helps narrow down solutions. We’ll cover the most effective fixes for all the common audio issues with Pluto TV across various devices.
Pluto TV competes with several alternative free streaming platforms like Samsung TV Plus, Xumo, and Freevee which also encounter periodic audio issues.
Video Streaming Requires Reliable Internet
Since Pluto TV is an internet-based streaming service, an unstable internet connection is one of the top reasons for video and audio disruptions.
- Minimum recommended internet speed for Pluto TV is 5 Mbps
- Connect your device directly to the WiFi router if possible
- Disconnect other devices using bandwidth to improve connectivity
- Restart router if connection drops frequently
Quick Fixes To Restore Sound
Before diving deeper, try these basic troubleshooting steps first to bring back sound on Pluto TV:
- Check volume settings – increase Pluto TV and device volume
- Play different video content as audio check
- Close and re-launch the Pluto TV app
- Reboot your device
- Re-connect external speakers and cables
- Clear the Pluto TV app cache and data
Often these simple measures can fix momentary glitches behind the no audio issues.
Adjust Volume Levels
Make sure your TV, phone or laptop volume isn’t set too low or muted. The Pluto TV app volume also needs to be turned up under Settings > Audio.
External speakers connected to your device should be powered on and volume increased as well.
Test With Different Video
Play alternative streaming or local video content on your device to check if audio works normally outside Pluto TV.
If other videos have sound, then the no audio problem likely lies with the Pluto TV app itself.
Reboot Device
Power cycling your smartphone, streaming box, smart TV or computer can refresh system processes and clear transient app glitches causing sound loss.
- For smart TVs, unplug from power, wait 1 minute, then reconnect
- For mobile devices, power off completely then restart
Pluto TV App Troubleshooting
Assuming connectivity and hardware are not at fault, the next place to troubleshoot is directly within the Pluto TV app.
Update Pluto TV App
Buggy app versions or outdated installations unable to handle newer video codecs can lead to playback failures.
- Install latest supported Pluto TV app from official app/play stores
- Manually check for updates via app Settings
- Enable auto-update if available
Updating also syncs your app data which may have become unsynced and corrupted similarly to issues where Pluto TV keeps freezing mid-stream.
Re-install Pluto TV App
If updating isn’t possible or fails to restore functionality, uninstall and reinstall the Pluto TV app from scratch:
- Android – Clear app data before reinstall
- iOS – Delete and redownload app
- Roku – Go to Manage App -> Uninstall
Reinstalling can wipe corrupt app data causing errors. Log back into Pluto TV after completing.
Clear Pluto TV Cache
Over time cache files, cookies and data get overloaded causing lags or freezing. Corrupted cache can also create playback failures.
To clear cache on Pluto TV:
- Android – Settings -> Apps -> Pluto TV -> Clear Cache
- iOS – Settings -> General -> iPhone Storage -> Pluto TV -> Offload App
- Smart TVs – Settings -> Apps -> Pluto TV -> Clear Cache/Data
Wiping the cache forces reloaded app files which may resolve software glitches.
Log Out and Back Into Pluto TV
Logging out resets app data tied to your account which could have become corrupted:
- Android/iOS – Tap profile icon -> Sign Out
- Roku – Pluto TV banner -> Manage Account -> Sign Out
- Smart TV – Account icon -> Sign Out
Then log back in and test playing videos.
TV and Audio Troubleshooting
If the standard Pluto TV app fixes don’t restore sound, further troubleshoot your streaming device and TV hardware.
Power Cycle TV and Devices
Sudden device freezes often relate to memory leaks in system processes. Forcing a reboot helps refresh.
Smart TV Troubleshooting
- Turn off TV via remote
- Unplug TV power cable for 1 minute
- Reconnect power cable, power back on
Streaming Device Troubleshooting
- Unplug streaming box power cable
- If no power cable, take batteries out of remote
- Wait 30 seconds then restart device
Allow device/TV to fully reboot before assessing.
Factory Reset TV
For recurring system-wide audio issues a full factory reset may be necessary:
- Accesses hidden recovery menu to reset device to default state
- Erases all stored app data including Pluto TV app
- Fixes corrupt software and firmware
How to Factory Reset a Smart TV
- Access TV recovery menu
- Select Factory Data Reset option
- Confirm reset
Refer device manual for exact reset procedure. Will require reconfiguring TV settings afterwards.
Factory reset can become necessary for devices like Amazon Firesticks where Pluto TV repeatedly struggles with audio, lagging channels or freezing.
Set Audio Output
If using external speakers, soundbars or AV receivers verify it is configured as the audio output source:
Select Audio Output on Smart TVs
- Go to Settings -> Sound -> Audio Out/Output
- Choose HDMI ARC, Optical, Bluetooth etc. based on speaker connection
Surround equipment must be powered on or configured as a paired device first.
Roku Audio Output
- Home Screen -> Settings -> Audio -> Audio Mode -> Stereo/Auto Detect
- Select device or headphone for private listening
Mismatched audio output is a common cause of no Pluto TV sound.
Adjust Audio Settings
Incompatible audio formats can also prevent sound. Check audio configurations:
Smart TV Audio Settings
- Settings -> Sound -> Advanced Settings
- Set Digital Audio Out format to PCM
- Turn off Dolby Digital Plus if available
- Toggle between Stereo and Auto audio modes
Roku Audio Settings
- Home -> Settings -> Audio -> Digital output format -> Auto
- Try alternating between Auto and Stereo
PCM is the most universally supported audio format.
Inspect Cables and Connections
Loose HDMI cables or faulty ports can cut out video and audio signal:
- If using AV receiver/soundbar, check HDMI and optical connections
- Make sure cables are fully inserted into ports on both ends
- Attempt different HDMI ports if available
- Try swapping cables to isolate defects
Visible corrosion, bent pins or loose ports indicate hardware damage.
Update TV/Device Software
Like apps, stale firmware can suffer compatibility setbacks:
- Smart TVs – Check Settings for System/Software updates
- Streaming devices – Visit device menu to search for firmware updates
- Enable auto update options if available
Continuous updates are key for maintaining optimized performance.
Internet Connectivity Fixes
Since Pluto TV streams over the internet, connection problems are a prevalent trigger for video and audio issues.
Reset Network Devices
If your ISP connection seems unstable, first renew network components.
- Reboot your wifi router and modems
- Power cycle networking devices even if router stays on 24/7
- Restore factory default settings if connectivity doesn’t improve
Reset steps depend on your specific networking hardware.
Check Internet Speed
Run speedof.me bandwidth test or apps like Google SpeedTest.
Minimum 5 – 10 Mbps needed for smooth Pluto TV streaming. Up to 25 Mbps recommended.
If your internet speed tests low:
- Disconnect other devices temporarily
- Move Pluto TV device closer to router
- If using wifi, switch to 5GHz band
- Contact ISP about upgrade options
Wired Connections Are More Reliable
For best results, use wired LAN connection instead of wireless:
- Smart TVs – Connect ethernet cable directly to router
- Streaming devices – Use adapter to enable wired internet
This prevents bandwidth drops and latency issues over WiFi.
Further Pluto TV Troubleshooting
If you’ve tried all other fixes with no improvement in Pluto TV audio, explore a few last resort options before seeking help.
Desktop Site
Attempt accessing Pluto TV through the web browser instead of the app.
Visit pluto.tv in a desktop browser and play video content.
This isolates problems stemming from the mobile/TV app itself. Video playback uses the browser’s media capabilities instead.
