If you've recently encountered the issue of no sound coming out of your Samsung TV's optical out port, then you're not alone. This is a common issue among Samsung TV owners.

Fortunately here at IbmiSoft, our Support Expert have outlined a few simple solutions that can help you resolve the problem. 

1. Enable the optical out feature

First, check to make sure that the optical out is enabled in the TV's audio settings. 

On most Samsung TVs, you can access the audio settings by pressing the Home button on the remote and then navigating to Settings > Sound > Expert Settings > Digital Audio Out. Make sure that the setting is set to Optical Out instead of PCM.

2. Securely connect the optical cable

• Next, make sure that the optical cable is securely connected to both the TV and the external device (e.g. soundbar or receiver).
• If the cable isn't properly connected, the optical out won't work.
• Check both ends of the cable and make sure that it is securely connected.
• If that doesn't solve the problem, try plugging the cables into different ports.
• If the cable is loose, try to reconnect it. If the cable is damaged, you may need to replace it.

3. Unplug the TV from the Wall power socket

If the optical out is enabled and the cable is connected, try unplugging the TV from the wall for a few minutes and then plugging it back in. This can sometimes reset the TV and fix any minor issues that might be preventing the optical out from working.

4. Perform Factory reset

If the optical out is still not working, the issue could be with the TV itself.

You can try resetting the TV to its factory settings by navigating to Settings > Support > Self Diagnosis > Reset. This will erase all of your settings and return the TV to its original state.

5. Check the Input Settings

The next fix to try is to check your Samsung TV's input settings. Make sure that the optical out option is enabled. If you're using a Samsung soundbar, you may need to select the soundbar as the TV's output device.

6. Update the Firmware

If your Samsung TV's optical out still isn't working, the next fix to try is to update the firmware. Samsung TVs usually update automatically, but you can also manually check for updates. To do this, you'll need to open the TV's settings and navigate to the "Support" menu.

7. Check the Soundbar Settings

If you're using a Samsung soundbar, you may need to check the soundbar's settings. Make sure that the soundbar is set to the correct input and output. If the soundbar is set to the wrong input or output, this could be causing the issue.

8. Check the Soundbar Cables

If you're using a Samsung soundbar, you may need to check the soundbar's cables. Make sure that the cables are securely connected to both your TV and your sound system. If the cables are loose, try to reconnect them. If the cables are damaged, you may need to replace them.

9. Reset the Soundbar

If your Samsung soundbar still isn't working, the next fix to try is to reset the soundbar. This will reset all of the soundbar's settings and might help resolve the issue. To reset the soundbar, you'll need to open the soundbar's settings and navigate to the "Reset" menu.

10. Check the Audio Settings

The next fix to try is to check your Samsung TV's audio settings. Make sure that the audio output is set to the correct mode. If the audio output is set to the wrong mode, this could be causing the issue.

11. Turn Off Any Audio Enhancements

If your Samsung TV's audio is still not working, the next fix to try is to turn off any audio enhancements. Some TVs have audio enhancements that can interfere with the optical out. If your TV has audio enhancements, try turning them off and see if that resolves the issue.
