Quick answer
• Check that Sound Output is set to TV Speaker or your connected audio device • Power cycle the TV by unplugging for 60 seconds • Update the TV software through Settings → Support → Software Update • Switch audio output to a different setting, then back to your preferred option
Symptoms
• No sound from the TV while video is playing • Sound works intermittently or cuts out • Audio settings appear correct but no sound is heard • Sound works on some apps but not others
Quick checks
Check the basics first: • Ensure TV volume is not muted or set to zero • Test different content sources (built-in apps, cable box, streaming device) • Verify external audio devices are powered on and set to correct input • Check all cable connections are secure
Step-by-step fix
Step 1: Configure audio output settings
- Press the Home button on your remote
- Navigate to Settings → Sound
- Select Sound Output and ensure it's set to TV Speaker or your connected device (Soundbar, Receiver)
- If using external audio equipment, confirm it's powered on and set to the correct input
- Try switching to a different audio output, then switch back to your preferred setting
Step 2: Power cycle the TV
- Turn off your Samsung TV using the remote
- Unplug the TV power cord from the wall outlet
- Wait at least 60 seconds
- Plug the TV back in and turn it on
- Test the sound across different content

If it still isn't working
If sound issues persist after these steps, you may have a hardware problem. Check if your Samsung TV is still under warranty and contact Samsung support for repair options. For out-of-warranty TVs, consult a professional technician for diagnosis. You can also try a factory reset through Settings → General → Reset, but note this will erase all your settings and require reconfiguration.
FAQ
Why does my Samsung TV have sound on some apps but not others? Individual apps can have separate audio settings or compatibility issues. Try clearing the app's cache or reinstalling problematic apps through the Smart Hub.
Can HDMI cables cause sound problems? Yes, faulty or loose HDMI cables can cause audio dropouts. Try a different HDMI port or cable to rule out connection issues.
Should I reset my TV to factory settings? Only as a last resort, since you'll lose all custom settings. Try the solutions above first, as they resolve most sound issues without data loss.
How do I know if it's a hardware problem? If sound doesn't work across all inputs, apps, and after software updates, and the TV is properly configured, it's likely a hardware issue requiring professional repair.
