All three outputs dead at once, speaker, Bluetooth, headphones, and not a single beep from your Galaxy Tab S9. Before you start worrying about a hardware fault, know this: the vast majority of Galaxy Tab S9 no sound cases we deal with at Vivid Repairs are a settings issue or a firmware glitch, and they're fixable in under half an hour. Work through this guide in order and you'll almost certainly have audio back before the end of it.
What Causes Galaxy Tab S9 No Sound?
When every audio output dies at once, that pattern is actually useful diagnostic information. A single dead speaker might mean a blown driver. But speakers, Bluetooth, and headphones all going silent together almost always points upstream, to something in the audio routing or configuration layer rather than a physical component.
The most common cause we see is muted or misconfigured settings. Samsung's audio stack has several independent mute controls: the volume sliders, the Mute all sounds toggle buried in Accessibility, Do Not Disturb, and focus modes. Any one of them can silence everything, and it's surprisingly easy to hit one by accident, especially if you've been adjusting accessibility settings or handed the tablet to someone else.
Second most common is audio routed to a device that's no longer there. If the Tab S9 last connected to a Bluetooth speaker or a USB-C audio adapter and that device is now switched off or out of range, the tablet can get stuck trying to output to something that isn't responding. The built-in speaker stays silent because the OS still thinks audio is going elsewhere. Disconnecting all Bluetooth devices usually sorts this one immediately.
Third-party apps are a proper nuisance here. EQ apps, sound boosters, and call recorder apps hook into the audio pipeline at a system level. Some of them, particularly older ones not updated for One UI 6, can corrupt the audio session for every app on the device. Booting into Safe mode is the quickest way to confirm or rule this out.
Below those, you've got firmware bugs (usually fixed by a software update or a restart), and at the bottom of the list, actual hardware failure of the speaker module or audio IC. Hardware is rare, and you'll only confirm it after a factory reset still leaves you with silence.
Galaxy Tab S9 No Sound Quick Fix
Start here. These steps take five to ten minutes and fix the problem in the majority of cases.
Check Volume, Mute Toggles, and Bluetooth Easy
- Open volume settings
Go to Settings then Sounds and vibration then Volume. You'll see separate sliders for Media, Ringtone, Notifications, and System sounds. Drag every slider up to at least halfway. It's common for the Media slider specifically to be at zero after a firmware update. - Turn off Mute all sounds
Go to Settings then Accessibility then Hearing enhancements. If Mute all sounds is toggled on, that kills every audio output on the device regardless of what the volume sliders show. Turn it off, then check your Quick Settings panel (swipe down twice) for any speaker or mute icon that looks active. - Disable Do Not Disturb
Go to Settings then Notifications then Do not disturb and switch it off. Also check Settings then Digital Wellbeing and parental controls for any active Focus mode, those can suppress audio too. - Disconnect all Bluetooth devices
Open Settings then Connections then Bluetooth. Disconnect every paired device. Then open a music app or YouTube and test the built-in speaker directly. If sound comes back, the tablet was routing audio to a Bluetooth device that wasn't actually available. - Restart the tablet
Hold the Side key and Volume down together for over 7 seconds. Wait for the full reboot, then test speaker, wired headphones, and Bluetooth in that order.

Still silent? These intermediate steps go deeper into the software layer. Budget 15 to 30 minutes.
Clear App Cache and Update Firmware Easy
- Check system sound toggles
Go to Settings then Sounds and vibration then System sound. Make sure touch sounds, keyboard sounds, and charging sounds are enabled. This confirms the audio stack is actually processing system-level audio, which helps you isolate whether the problem is app-specific or system-wide. - Clear cache for media apps and Media Storage
Go to Settings then Apps. Find the app you're testing with (YouTube, Spotify, etc.), tap Storage, and hit Clear cache. Then search for Media Storage in the app list, tap it, and clear its cache too. Corrupted cache in Media Storage is a known cause of Galaxy Tab S9 no sound in media apps specifically. - Update system software
Go to Settings then Software update then Download and install. Samsung regularly pushes audio stack fixes in One UI updates. If there's a pending update, install it and restart. This one often needs a second reboot before it fully sticks, so restart twice if the first reboot doesn't restore audio.
Boot into Safe Mode to Isolate Third-Party Apps Medium
- Enter Safe mode
Press and hold the power button until the power menu appears. Press and hold the Power off option on screen. A prompt will appear asking if you want to boot into Safe mode. Tap it. The tablet restarts with all third-party apps disabled. You'll see 'Safe mode' in the bottom-left corner of the screen. - Test audio in Safe mode
Open the stock Samsung Music app or play a notification sound. If Galaxy Tab S9 no sound is suddenly fixed in Safe mode, a third-party app is causing it. If it's still silent in Safe mode, the problem is in the core OS or hardware, and you can skip to the factory reset step. - Identify and remove the offending app
Exit Safe mode by restarting normally. Think about what you installed recently, especially EQ apps, sound boosters, call recorders, or anything that requests audio permission. Uninstall those apps one at a time, testing audio after each removal. According to HowToGeek's Android audio guide, audio modifier apps are one of the leading causes of system-wide sound loss on Android tablets.
Advanced Galaxy Tab S9 No Sound Fixes
If you're still here, the quick and intermediate fixes haven't cracked it. These steps are more drastic but they cover the remaining software causes before you start thinking about hardware.
Factory Reset the Galaxy Tab S9 Hard
- Back up everything first
Go to Settings then Accounts and backup then Back up data. Back up to Samsung Cloud or a Google account. Also manually copy any files, photos, or documents to a PC or cloud storage. A factory reset wipes everything on the device. - Run the reset
Go to Settings then General management then Reset then Factory data reset. Read the warnings, confirm your Samsung account password if prompted, and let it run. The process takes 5 to 10 minutes. - Test audio before restoring anything
This step is critical. When the tablet boots fresh, test the speaker, headphones, and Bluetooth before you sign back into your Samsung account or restore any apps. If audio works on a clean device, the problem was in your configuration or a restored app. If audio is still dead on a completely clean device, it's hardware.
Windows Audio Troubleshooting (If Using Tab S9 as PC Audio Output) Medium
- Set the correct output device in Windows
Right-click the speaker icon in the Windows taskbar and choose Sound settings. Under Output, make sure the correct device is selected. If the Tab S9 is connected via USB or Bluetooth, it may have been set as the default output and then disconnected, leaving Windows with no valid output device. Switch back to your PC speakers or headphones. - Check Windows Audio services
Press Windows key + R, typeservices.msc, and hit Enter. Find Windows Audio and Windows Audio Endpoint Builder in the list. Both should show Status as Running and Startup type as Automatic. If either is stopped, right-click it and choose Start. If they keep stopping, a system file may be corrupted. - Run the Playing Audio troubleshooter
Go to Settings then System then Troubleshoot then Other troubleshooters. Run Playing Audio and let Windows attempt an automatic fix. It catches misrouted audio and stopped services more often than you'd expect. - Reinstall or roll back the audio driver
Open Device Manager (right-click Start then Device Manager). Expand Sound, video and game controllers. If you see a yellow exclamation mark, right-click the device and choose Update driver. If the problem started after a recent Windows Update, try Roll back driver instead from the Driver tab in Properties. For persistent driver issues, download the latest audio driver directly from your PC or motherboard manufacturer's support page rather than relying on Windows Update. Our Windows audio driver reinstall guide covers the full process step by step.
When It's a Hardware Fault
Here's the hard truth: if you've done a factory reset and the Galaxy Tab S9 no sound problem is still there across every output, speaker, wired headphones, and Bluetooth, the fault is almost certainly physical. The speaker module, audio IC, or the headphone/USB-C connector has failed.
At that point, stop. Don't try to open the tablet yourself. The Tab S9 uses a tight laminated build and the speaker assembly is not a user-serviceable part. You'll need to visit a Samsung Service Center or an authorised repair shop. If the tablet is under warranty, Samsung will cover a genuine hardware fault. If it's out of warranty, get a quote before committing, speaker module replacements on the Tab S9 are a reasonable repair cost compared to a replacement device.
For any physical repair that goes beyond software, including speaker replacement, connector damage, or audio IC issues, our Samsung tablet repair page explains what to expect from a professional repair and how to check whether your device is still under warranty.
Preventing Galaxy Tab S9 No Sound
Most of the cases we deal with are preventable. Here's what actually matters, in order of importance.
Keep the firmware current. Samsung pushes audio stack fixes regularly and skipping updates is the single biggest reason people end up with recurring sound issues. Set Software update to download automatically under Settings then Software update then Auto download over Wi-Fi.
Be selective about audio apps. EQ tools, sound boosters, and call recorders hook deep into the Android audio pipeline. If you don't actively use one, don't have it installed. If you do use one, check it has been updated for your current One UI version before installing. The Samsung Safe mode guide is a good reference if you ever need to diagnose an app conflict again.
Check your output device after every Bluetooth session. When you disconnect a Bluetooth speaker, glance at the Quick Settings panel and confirm the audio icon shows the built-in speaker is active. Takes two seconds and prevents the 'routed to a missing device' issue entirely.
Restart after major updates. One UI updates sometimes leave the audio stack in a half-initialised state. A fresh reboot after any firmware update clears that. And back up your data before any factory reset or repair, not after you've already decided you need one.
Galaxy Tab S9 No Sound: Summary
Galaxy Tab S9 no sound is almost always a software problem, and a solvable one. Start with the volume sliders and mute toggles, disconnect Bluetooth, and restart. If that doesn't fix it, clear the media app cache, update the firmware, and boot into Safe mode to rule out third-party apps. A factory reset clears the remaining software causes. If audio is still dead on a clean device, you're looking at a hardware fault and need a professional repair. Work through the steps in order and you'll almost certainly have sound back long before you reach that point.
