If you are looking to learn more about TCL Roku TV optical audio out settings, without having to dig deep into the manufacturer’s documentation, you’ve found the right post.
All the movies and TV shows that are accessible through Roku streamers now come with surround audio.
Here we will unveil everything about the Digital Optical Audio Out (S/PDIF) in detail and let you know how you can use it.
There is a lot to discuss today so shall we get started?
The Digital Optical Audio Out of your Roku TV is used to output audio for surround sound formats such as Dolby Digital or DTS. Since some soundbars and AVRs do not support HDMI inputs you can still use the optical audio out.
To do so you will need a TOSLINK optical cable which is not provided in the box.
Connect one end to the TV optical input and the other end to your soundbar or whatever device you’re planning to listen to audio with.
Even though it sounds really an issue at first glance, you may stumble upon a variety of issues that we are going to discuss in a moment.
TCL Roku TV Optical Audio Out Settings Explained
There are not many settings you can play with when it comes to digital optical audio output.
By pressing the Home button on your remote and navigating the Settings, you should be able to see a tab labeled “Audio”.
There you can choose between HDMI and S/PDIF, for optical audio out.
You can press on “Auto Detect” in order for your TV to detect if there is an optical output.
Some applications & channels such as Netflix might not use the optical output by default.
Specifically for Netflix, you might need to select the “English (5.1)” under the “Audio and Subtitles” tab.
More About Formats
Different devices such as soundbars, AVRs, and TVs usually support different audio formats.
Some may be able to decode only Dolby Digital Plus, others Dolby Digital (Dolby D) or Dolby ATMOS.
To understand which formats are supported for your specific device, navigate to the user manual or the dedicated customer service.
Some applications are set to use a default decoder, and if your TV settings are set to use another decoder you might have audio issues.
Now when you know where to look for the digital optical audio out, let’s see how to connect it.

TCL Roku TV Optical Out Not Working?
Once the Roku TCL TV optical audio out is connected you might be having trouble with one of two things.
Either you don’t hear audio or your video disappeared after connecting the optical audio.
If this is the case, you don’t need to worry as we got you covered with a few troubleshooting steps below.
You Don’t Hear Audio
If there is no audio coming through the optical output of your Roku TV, follow the steps bellow
- Take your Roku remote and press the Home button
- Navigate to Settings and then select Audio
- Instead of choosing “Auto Detect” select a setting that matches your TV/AVR or soundbar capabilities
You can check which audio formats are supported in your device user manual/documentation.
The other way around would be to contact your manufacturer and ask for more information.
It is really important to ensure your device’s optical (or S/PDIF) audio out is assigned to the correct audio input source.
Learn how to assign an audio source for your specific device and if it is even supported.
You Don’t See Video
If you don’t see video on connecting your optical audio out, here are a few things to ensure before you jump to conclusions.
- If you are running video through a soundbar or AVR, check if the right input is selected
- Ensure that the correct input is selected on your TV
- Inspect all cable functionality (ensure that all connections are secured and they are firmly attached to the rightful ports
It is highly unlikely for the video issue to be related to the optical out, so if the issue continues, we recommend disconnecting everything and starting over.
You might have connected something wrong in efforts to troubleshoot the issue.
