What are the Specifics to Connecting Your Soundbar to TCL TV?

You need to figure out which connection form you wish to use. Use the optical cable if it’s available. Use HDMI if it’s not. If your soundbar only has an optical port and your TCL TV only has an HDMI port then you need to get an adapter or converter. Otherwise, just use the optical port.

To make things easier, we’ve condensed the process of connecting your sounder to your TCL TV into a few simple steps as outlined below.

  • Optical Cable Ports: You can either have an SPDIF or TOSLINK port, which should be indicated by your TCL TV and sounder. There are soundbars that accept HDMI connections too, so you merely need the second HDMI port or an HDMI splitter to connect to these soundbars.
  • HDMI vs. Optical: HDMI connections allow for higher quality connections that are much better than optical. HDMI cables are also less likely to stop functioning to pinching or bending its interior wires. This is in contrast to optical or fiber-optic cables that should be laid straight.
  • Setup the Settings: Turn on the TV once you’ve plugged the cables to their proper ports. From there, you’ll have to put in the correct settings. To be more specific, choose the connection you have to have the TV recognize the soundbar (RCA audio, digital optical, or HDMI arc).
  • Enable Connection: To recap, connect the soundbar to your TCL TV, turn on both devices, turn on the settings on the television, click on “Control Other Devices”, enable the connection (“Optical”), pull up on the main menu your system audio control, and finish up.
  • Return Home: Go back to the home screen then test your soundbar by playing the movie. It should work fine if you’ve connected and set it up properly. Roughly the same setup is involved for HDMI or Bluetooth connections. Just choose the “HDMI” or “Bluetooth” slots.

What Should You Watch Out for When Connecting Your Soundbar to TCL TV?

After double-checking and securing the connections, test the sound by playing a movie or turning on Spotify. You can even open the YouTube app, listen to podcasts, or play online radio depending on which apps you have downloaded.

Should You Connect Your Soundbar to Your TCL TV with an Optical Cable?

How Do You Connect Your Soundbar to the TCL TV without HDMI?
