Let’s jump in!
Set Audio Output to Optical
When you connect your external speakers to your Samsung TV, the audio output doesn’t automatically change to be played through the speakers.
As the audio output is set to the TV speakers by default, you need to change it to the external speakers to get sound.
How are you supposed to do that? Follow the simple steps below:
- Press on the Menu button of your Samsung TV remote and you’ll be taken to the settings.
- Find out the “Sound Section” in the settings.
- There you will find the “Sound Output” option and you will see that it’s set to TV speakers by default. Change it to Optical.
If this was your issue, then you can expect your speakers to start playing sound. If this wasn’t the problem, take a look at the other probable issues below.
Change Audio Format in the Expert Settings
If changing the audio output doesn’t do the job, there is another thing you need to look into. And that’s the audio format.
For your Optical Audio Out to work, your audio format has to be in PCM audio format. But by default, the audio format is set to HDMI Input audio or Digital Output audio.
You need to change it in the following process:
- Go to the “Sound Section” in the Menu Settings of your TV.
- Find out “Expert Settings”.
- There you’ll see HDMI Input Audio and Digital Output Audio. Change both of them to PCM audio.
And that’s how you can change your audio format to the correct one for your external speakers to work.
Change TV Audio Sound Settings
You can’t forget to change the TV audio sound settings to Digital Out for your external speakers to work.
Don’t know how to do so? Follow the steps below:
- Go to your TV’s Sound Settings.
- There you need to select Audio Out.
- Out of all the options, select Optical.
- After clicking on Optical, more options will be shown, from which you need to select “Digital Out Sound”.
If you adjust all the above-mentioned settings properly in your Samsung TV, then you’re supposed to be able to make your external speakers work properly.
In case you’re still unable to make your External Speakers produce sound, you have a few more matters to look into. Keep reading!
Didn’t Work? Check These Out
All the prerequisites are met and your settings are on-point. But you’re still unable to use the Audio Out/ Optical function. What can be causing it?
When the issue is not with the settings, there can be technical issues responsible for the Optical Out no sound issue. It’s not only in the case of Samsung TV, there are similar issues like the Vizio sound bar not turning on.
Below, I’ve mentioned some of the most common technical problems and remedies for you to check and solve.
Defective Optical Cable
When all the settings are right, the problem could be a defective optical cable, which is preventing your external speakers from producing sound.
Hence, don’t forget to check whether or not your optical cable is functioning. If you find that it isn’t, then replace it with a high-quality optical cable.
On that note, here are some high-quality optical cables suitable for your Samsung TV:

Defective Optical Port
All the settings are on-point and your optical cable is also working. Then what could be the matter?
The problem can be a faulty port. Make sure to check the ports on your Samsung TV that connect to the external speakers or the optical cable.
If there is an issue with the ports, then contact the helpline to fix it.
Remove Power Completely
It can be quite annoying to see a device failing to do the main job it’s supposed to do. Like when the AirPods mic stops working.
After going through all the probable issues I’ve mentioned so far, if you can’t figure out the exact reason behind the problem, you can try an old-fashioned method.
Sometimes, the toughest of issues can be solved by completely removing power from the device and then bringing it back after some time.
What you need to do is turn off your TV and unplug it from the power source. Keep it unplugged for about 5 to 10 minutes. Then connect it back to the power source.
If the problem persists, you can also try factory resetting your TV.
That’s all!
