1. Check the Volume and Sound Settings

Ensure that the phone’s volume isn’t muted and the correct output is selected.

Press the Volume Up button multiple times to increase the volume.
Swipe down from the top of the screen and tap the Speaker icon to ensure it’s not muted.
Navigate to Settings > Sounds and Vibration and adjust the volume sliders.

2. Restart Your Phone

A simple restart can fix minor software glitches that may be affecting the speakers.

Press and hold the Power button.
Tap Restart and wait for the phone to reboot.
Check if the speakers are now functioning properly.

3. Disable Bluetooth

Your phone might be connected to a Bluetooth audio device, redirecting the sound.

Swipe down from the top of the screen to open Quick Settings.
Tap the Bluetooth icon to disable it.
Try playing audio to see if it comes through the speakers.

4. Check for Do Not Disturb Mode

Do Not Disturb mode can silence all sounds, including media playback.

Go to Settings > Notifications > Do Not Disturb.
Ensure that Do Not Disturb is turned off.
Try playing a sound to check if the issue is resolved.

5. Test the Speakers Using the Diagnostic Tool

Samsung has a built-in diagnostic tool to check the hardware.

Open the Samsung Members app.
Tap Get Help, then select Diagnostics.
Choose Speaker Test and follow the instructions.
If you don’t hear any sound, it might be a hardware issue.

6. Clear Cache for Media and Audio Apps

Corrupted cache files in media apps can cause audio issues.

Go to Settings > Apps.
Select an app that plays audio (e.g., Spotify, YouTube, or Samsung Music).
Tap Storage, then select Clear Cache.
Repeat for other media apps and test the speakers again.

7. Boot into Safe Mode

Safe Mode disables third-party apps that might interfere with the speakers.

Press and hold the Power button.
Tap and hold Power Off, then select Safe Mode.
Check if the speakers work in Safe Mode.
If they do, uninstall any recently installed apps that may be causing the issue.

8. Clean the Speaker Grilles

Dust or debris in the speaker grilles can block sound output.

Use a soft-bristled brush or a toothpick to gently clean the speaker openings.
Blow compressed air (gently) to remove dust.
Avoid using liquids, as they may damage internal components.

9. Update Your Software

A software bug might be causing the audio issue, and an update could fix it.

Go to Settings > Software Update.
Tap Download and Install to check for updates.
If an update is available, install it and restart your phone.

10. Reset Sound Settings

Resetting sound settings can restore default audio configurations.

Open Settings > General Management.
Tap Reset > Reset all settings.
Confirm the reset and restart your phone.
Check if the speakers work after the reset.

11. Test with Headphones

Checking if sound plays through headphones can help identify the issue.

Plug in wired headphones or connect Bluetooth earphones.
Play any audio file.
If sound plays through headphones but not the speakers, the speaker hardware might be faulty.
