Your Samsung TV’s optical audio out allows you to output digital audio (PCM or Dolby Digital) from a soundbar or external speakers when visual content contains this feature.
If you’re having issues with the optical audio output on your Samsung TV, there are a few steps you can take to fix the issue. These include changing settings, checking the connection and using another optical cable.
Check the Connection
If your Samsung TV is not receiving sound when connected external speakers via optical cable, there may be an issue with the connection. This can be caused by various reasons such as incorrect settings on your television or sound system, damaged cables and connections, or an ailing A/V receiver.
Optical audio is an audio output on your television that transmits data using fiber optic cable instead of copper-based cables. This enables high-quality, lossless sound transmission and makes optical audio ideal for connecting external speakers or home theater systems.
To check if your Samsung TV is working with an optical cable, locate the “Audio Out Optical” port on the back. It looks like a miniature home plate and has a hinged door on one side that you can open to access the port.
Once you locate it, plug the end of your optical cable into the port. This should make a clicking sound and allow you to hear audio from external speakers or soundbars.
You can also try disconnecting the optical cable from your external speaker and connecting it through an analog audio cable instead. This should solve the issue and give you a better indication of whether or not your optical cable is functioning correctly.
If your Samsung TV’s optical out is still giving you problems, try resetting its audio settings to their default values by pressing the menu button on your remote and selecting either “Audio” or “Sound” from the list.
Android TV(tm) and Google TV(tm) models offer the option to change the sound output format from PCM or Dolby Digital depending on which sound system you have. After making changes, save them and turn your television back on again.
If your Samsung television’s optical out is still not functioning properly, it may be time for a factory reset. This will clear all internal settings and those for external devices on the television, restoring all features and functions you paid for.
Check the Settings
When connecting external audio devices to a Samsung TV, there are a few settings you should adjust in order to get the optimal sound quality. These can make an enormous difference in how your television sounds, so be sure to check them regularly for optimal performance.
First, verify your optical cable is working properly. Make sure it’s plugged in securely and connected to both your TV and sound system. If not, you may need to replace the optical cable with a new one.
Next, ensure the optical out is set to either PCM or Dolby Digital (depending on your sound system). This will guarantee optimal audio transmission from your TV to speakers without any problems.
To do this, open your TV’s audio/sound settings and select Audio Out. In this section, you’ll see a drop-down list with options like HDMI ARC and Internal TV Speakers.
Once you select Optical, a separate menu will open with expert settings. In order to get the audio working properly, all of these must be changed to PCM.
Make sure your HDMI input and output are both set to PCM, so your TV can pass high-resolution audio like that found on Blu-ray movies.
Finally, try playing an audio file through your TV speakers to verify if there is no problem with optical out or any associated settings or connections. If it works, there’s likely nothing wrong with your optical out connection or settings.
Finally, if you don’t hear any sound coming from your speakers when using an optical cable to plug in, something may be amiss with your Samsung TV. This could be either a hardware or software issue so be sure to address this ASAP before creating further issues.
Check the Optical Cable
Optical cables are used to link audio devices such as DVD players, cable boxes and soundbars to your Samsung TV. This type of cable utilizes fiber optics for data transmission, eliminating noise generated by copper-based audio cables.
If your Samsung TV’s optical out is malfunctioning, it could be due to a cable issue. This could be caused by any number of causes, such as faulty connections or an incorrect setting.
Before connecting any devices, it’s essential to inspect the optical cable. Make sure the connector aligns properly with the port and there are no foreign particles present in it. Doing this will guarantee a stable and uninterrupted connection.
Some TVs feature caps on their optical ports to prevent dust and other particles from contaminating them. You can remove these caps and clean the port with cotton swabs or compressed air.
Another thing to check is whether the port has been plugged in correctly. You should be able to feel the cable fitting into the port when plugged in, so be sure not to force it in.
Test the optical cable to confirm it’s functioning correctly by plugging it into an external speaker or soundbar and listening to the audio output. With a high-quality optical cable, sound should be crystal clear and loud.
If the issue persists, replacing your cable may be necessary. You can do this by contacting the manufacturer for instructions or shopping online for replacement cables.
Additionally, you can try resetting the settings on your TV or sound system to resolve any problems with optical out audio. To do this, navigate to the menu and select “Reset Audio Settings” or something similar (this option may differ depending on which model).
After clearing your settings, you should be able to connect your device to your Samsung TV and hear audio clearly. You may need to update the software on your television in order for this functionality to remain stable.
Check the Video Cable
If your TV has an optical cable, double-check to see if it is securely attached. If not, there may be a fault with the cable or one of its ports on your television set. In such cases, a new optical cable may need to be purchased.
Optical cables are commonly used to transmit audio from your television to a soundbar or external speakers. When watching video content with Dolby Digital or PCM audio, standard cable and analog stations do not support this type of sound, so to listen to these formats you need an optical cable connected directly to a quality soundbar.
When connecting an optical cable to your television, make sure the connectors are correctly aligned and both ends of the cable have a red light. Incorrect connections can damage your television or prevent signal reception.
Some televisions require that the internal speakers be turned off before outputting audio from the TV to an external speaker or audio system. To disable these, select Settings > Sound or Speakers then choose External Speakers or Audio System from the menu.
Another way to confirm if your optical cable is functioning properly is by plugging it into another device and checking if the signal is being transmitted. You could also connect it to another television or soundbar to see if that works as well.
Your Samsung TV’s optical output may depend on the type of cable you are using. Composite and component cables both transport video signals, but their functions differ.
Optical cables are more delicate than coaxial ones, so if you plug them into the wrong port or forcefully insert the cable, the damage could occur. Before connecting anything, be sure to unplug any other peripherals you have connected to your computer or TV so you can identify which one is causing issues.
