Step by Step Tutorial: Using Optical Audio from Streaming to a TV

Before we dive into the steps, let’s quickly chat about why this is worth your time. Using an optical audio cable can enhance your TV’s sound quality, giving you clear, crisp audio that’s a step up from standard HDMI or RCA cables. Let’s get started!

Step 1: Check Your TV and Streaming Device for Optical Audio Ports

Look for a port labeled “Optical Audio,” “Digital Audio Out,” or something similar on both your TV and streaming device.

Most modern TVs and streaming devices, like Roku or Apple TV, have these ports. They’re usually marked with a distinct red light.

Step 2: Purchase an Optical Audio Cable

Buy an optical audio cable if you don’t already have one. They’re readily available online or at your local electronics store.

Make sure to buy a cable that’s long enough to reach from your streaming device to your TV without stretching.

Step 3: Connect the Optical Audio Cable

Plug one end of the optical audio cable into the port on your TV and the other into your streaming device.

You’ll hear a small click when the cable is properly connected. Be gentle, as the connectors can be delicate.

Step 4: Change Your TV’s Audio Output Settings

Go into your TV’s settings menu and set the audio output to “Optical” or “Digital Out.”

This setting redirects the audio from the TV’s built-in speakers to the optical cable.

Step 5: Enjoy Your Enhanced Audio

Start streaming your favorite show or movie and enjoy the improved sound quality.

You should immediately notice a difference in the audio quality, with a cleaner and more dynamic sound.

After completing these steps, you’ll be all set to enjoy your favorite shows and movies with much-improved sound quality. No more struggling to hear dialogue or missing out on subtle sound effects!
