What is Audio Out Optical Out on Samsung TV?
The audio optical out on Samsung TV is designed to output high-quality sound when the visual content you’re watching contains digital audio( PCM or Dolby Digital® technology). You’ll find this feature in some digital broadcasts as well as streaming videos.
Standard cable or analog stations don’t support it.
That’s why you’ll need to connect your Samsung TV to your soundbar or external speakers via a quality optical cable when you want to watch a video that contains digital audio. Of course, as we’ve said, you also need to fine-tune the TV’s settings to get sound from the connected devices.
How to Fix Samsung TV Optical Out No Sound?
1. Change Audio Output
The sound output of Samsung TVs is set on the TV speakers by default. If you connect the TV set to your external speakers without changing this, you’ll get no sound. To fix this, you need to:
- Go to the TV’s Menu Settings.
- Navigate to the Sound Section.
- Set the sound output to Audio out/Optical(instead of TV speakers).
2. Go to Expert Settings
If your Samsung TV refuses to produce sound after you’ve changed the audio output, there could be an issue with your default audio formats. Optical audio out won’t work if you are using digital output audio and HDMI input audio format. Here are the steps to follow to replace them with the correct audio format:
- Go back to the Sound Section.
- Navigate to Expert Settings.
- Go to HDMI Input Audio and Digital Output Audio and change each of them to PCM.
3. Change Audio/Sound Settings
You need to select digital out for the external audio devices to produce sound. To do so, you should:
- Go to your Samsung TV’s Audio/ Sound Settings.
- From the drop-down list, click on Audio Out and then select Optical (you’ll see several other options like Internal TV Speakers and HDMI ARC. You shouldn’t choose any of these alternatives).
- After choosing Optical, you’ll see another drop-down list. Scroll down and select Digital Out Sound (PCM).
4. Test Audio
At this point, you’ve adjusted all the settings as required. If your TV set is in the proper working order, you should start getting high-quality sound from external sound devices.
If that’s not the case, play any audio on the TV and listen to determine whether audio comes from the external speakers or soundbars.
Why Is There No Sound Coming from My Samsung TV? (I have Changed the Optical Out Settings)
If you still hear no sound after adjusting the settings required for your external speakers to produce sound, other unrelated issues could be with your speakers or Samsung TV. Here are the tips that might help you to fix the problem once and for all:
Test Your Optical Cable
You may be using a faulty optical cable—test whether that’s the case. You can alternatively plug a new optical cable into the television and see whether it works.
Check the Ports
If there is a problem with the ports of your external speakers or your Samsung TV, all the effort might never bear fruit. Ensure they are in their best form.
Power Cycle Your Samsung TV
If the ports are functional, temporal errors could be responsible for the problem. To fix them, you should do this:
- Turn off the TV.
- Unplug the device from the wall.
- Wait for approximately 5 minutes to let any lingering charge in the TV’s memory or capacitors fade.
- Plug the Samsung TV set back in.
- Turn the TV on again.
If you’ve followed the steps and your optical cable has no issue, you can factory reset the TV. Consult your user’s manual for instructions designed for your TV model.
How Do You Test An Optical Cable?
You can quickly test your Samsung TV’s optical cable if you use the VFL (Very Low Frequency) technique.
If you see a lot of red light, the cable is, and you should replace it. That’s the same case if you look from the other and see the whole ferrule glowing. On the other hand, you have a suitable cable if the light is coming only out of the fiber.
The simplest way to test whether you have an excellent optical cable is to replace it with a new one and see the outcome. If you notice some visible damage, you don’t need to test the cable. Replace. Check out the list of the Best Streaming Devices on Amazon now!
If your Samsung TV produces no sound with the optical cable, check whether you’ve correctly made the relevant setting changes and are using a high-quality cable. If you’ve done everything right but can’t hear sound from the external speakers, you are likely a victim of a hardware issue.
