Can You Connect Speakers To A TV? | Wired Or Wireless

Modern televisions keep getting thinner, which often means the built-in speakers sacrifice depth and volume for a sleek design. Adding external audio gear is the single best upgrade you can make for movie nights or gaming sessions. You do not need a degree in audio engineering to make this work; you just need to match the ports on your TV to the inputs on your speakers.

Most TVs released in the last decade offer at least two ways to send sound out. The method you choose depends on the cables you have lying around and the age of your equipment. We will walk through every connection type, starting with the highest quality options and moving to legacy fixes for older sets.

Identify Your TV Audio Outputs First

Before you buy cables or a soundbar, look at the back or side panel of your television. Manufacturers label these ports clearly, but they can look similar. You are looking for a port labeled “Out,” “Output,” “ARC,” or an icon of a pair of headphones.

Common ports you might find:

• HDMI ARC/eARC: Look for an HDMI port specifically labeled “ARC” or “eARC.” This is the current standard for high-quality audio.
• Optical (Toslink): A small, square port often covered by a flap that glows red when the TV is on.
• RCA Analog: Red and white circular jacks. Note that many modern TVs have these only as inputs, not outputs. Look for “Audio Out.”
• Headphone Jack (3.5mm): A standard small circular hole, often labeled with a headphone icon.
• Bluetooth: found in the settings menu, not a physical port.

Method 1: HDMI ARC Or eARC (Best Quality)

HDMI ARC (Audio Return Channel) is the superior choice for modern setups. It allows a single HDMI cable to send video to the TV and pull audio back to your soundbar or receiver. If your gear supports eARC (Enhanced Audio Return Channel), it can even handle uncompressed, high-bandwidth formats like Dolby Atmos.

Why Use This Method

HDMI ARC supports CEC (Consumer Electronics Control). This means your TV remote can control the volume of the external speakers automatically. You won’t need to juggle two remotes just to turn the sound down.

How To Connect via HDMI ARC

1. Locate the ARC ports — Find the HDMI port labeled “ARC” or “eARC” on both your TV and your sound system.
2. Connect the cable — Plug a high-speed HDMI cable into both ports.
3. Adjust TV settings — Go to your TV’s Settings menu, select Sound, and change the Sound Output to “HDMI ARC” or “Receiver.”
4. Enable CEC — In your system settings, make sure CEC (often called Anynet+, Bravia Sync, or SimpLink) is turned on so the remotes talk to each other.

Method 2: Digital Optical Cable (Reliable Alternative)

If your speakers do not have an HDMI input, or if you have used all your HDMI slots for consoles and streaming sticks, the optical cable (Toslink) is your next best bet. It sends a digital audio signal using light. While it cannot carry high-bandwidth formats like Dolby Atmos, it handles 5.1 surround sound perfectly.

Optical cables are thin and fragile. Avoid bending them sharply, as this can break the fiber optic core inside.

Steps For Optical Connection

1. Remove protective caps — Optical cables often come with tiny plastic tips covering the connectors. Pull these off before trying to plug them in.
2. Insert the cable — Plug one end into the “Digital Audio Out (Optical)” on the TV and the other into the “Optical In” on your speakers. Listen for a distinct click.
3. Set audio output — Navigate to Settings > Sound > Sound Output and select “Audio Out/Optical.”

Quick troubleshooting: If you hear a buzzing noise or no sound at all, check your TV’s “Digital Output Audio Format” settings. Switch it from “Dolby Digital” to “PCM.” Some older stereo speakers cannot decode Dolby signals, and PCM forces the TV to send simple stereo sound that any speaker can play.

Method 3: Bluetooth Connection (Wireless Convenience)

Wireless setups keep your entertainment center clean. Many smart TVs now include a Bluetooth transmitter specifically for audio. This is ideal for connecting a portable speaker or a pair of headphones for late-night watching, though audio quality is slightly lower than a wired connection.

Pairing Your Speakers

The menu path varies by brand, but the process is generally the same. Here is how to handle it on major brands:

• Samsung: Go to Settings > Sound > Sound Output > Bluetooth Speaker List. Put your speaker in pairing mode, then select it on the screen.
• LG: Go to Settings > Sound > Sound Out > Bluetooth.
• Sony (Android/Google TV): Go to Settings > Remotes & Accessories > Pair accessory.
• Roku TV: Go to Settings > Remotes & devices > Wireless headphones (or “Bluetooth devices” on newer models).

Handling Lip-Sync Latency

Bluetooth inevitably introduces a slight delay between the video and the audio. If you notice the actors’ lips moving before you hear their voices, look for an “Audio Sync” or “Delay” setting in your TV’s sound menu. You can often adjust a slider to line the audio back up with the picture.

Method 4: Analog connections (RCA And 3.5mm Aux)

Older televisions and vintage Hi-Fi systems rely on analog signals. If you are connecting a pair of powered bookshelf speakers or an old stereo receiver that lacks HDMI or Optical, these ports are your friends.

Using The Headphone Jack (3.5mm)

This is the simplest analog method. It uses the same cable you use for wired headphones.

1. Plug in the cable — Insert the 3.5mm jack into the headphone port on the TV.
2. Connect the speakers — Plug the other end into the “Aux In” or “Line In” on your speaker.
3. Check volume levels — Your TV might treat this connection as headphones. You may need to turn the TV volume up to 50% or higher to send a strong enough signal to the speakers.

Using RCA Cables (Red And White)

Be careful here. Most modern TVs have Red/White RCA ports, but they are usually inputs for old DVD players, not outputs for sound. Inspect the label closely. It must say “Audio Out.”

If your TV has RCA outputs:

1. Match the colors — Plug the red connector into the red port (Right channel) and white into white (Left channel).
2. Connect to amplifier — Run the other end to the “Tape In,” “Aux,” or “CD” input on your receiver.
3. Disable TV speakers — Analog connections often do not automatically mute the TV. You might hear sound from both. Go into settings and turn “TV Speakers” to Off.

How To Connect Speakers To A TV Without Audio Outputs

Budget TVs sometimes drop audio outputs to save costs. You might check the back panel and find nothing but HDMI inputs. You are not out of luck; you just need a middleman device called an HDMI Audio Extractor.

The HDMI Audio Extractor Method

This small box sits between your source (like a cable box, Roku, or PlayStation) and your TV. It splits the signal, sending video to the TV and audio to your speakers.

Setup instructions:

1. Connect source to extractor — Plug your streaming stick or console into the “HDMI In” on the extractor box.
2. Connect extractor to TV — Run an HDMI cable from the “HDMI Out” on the extractor to your TV.
3. Connect speakers — Use the optical or 3.5mm port on the extractor to plug in your sound system.

This bypasses the TV’s internal audio processing entirely. It works well, but you lose the ability to control volume with your TV remote. You will need to use the speaker’s remote control.

Troubleshooting Common Sound Issues

Even with the right cables, software settings can trip you up. If you have connected everything physically but hear silence or strange noise, check these settings.

Format Mismatch (PCM vs. Bitstream)

If you use Optical or HDMI ARC and hear a static crackling noise, your TV is likely sending a surround sound signal (Bitstream/Dolby) that your speakers cannot decode. This is common with simple 2.0 stereo setups.

The Fix: Go to Sound Settings > Expert Settings > Digital Output Audio Format. Change this to PCM. This converts all audio to a standard format that works on virtually every speaker.

TV Speakers Are Still On

Sometimes the TV continues playing sound through its internal speakers even after you connect an external set, creating an echo effect.

The Fix: Look for a “Speaker Select” option in the sound menu and switch it from “TV Speaker” to “Audio Out” or “Optical.” If that option does not exist, simply turn the TV volume down to zero. Since your external speakers have their own volume control, this silences the TV without muting the external audio.

Can You Connect Wireless Headphones And Speakers At The Same Time?

Some users want to use headphones for hearing assistance while the rest of the family listens through the speakers. Standard Bluetooth connections usually disable other audio outputs, but specific features allow dual audio.

Multi-output accessibility settings:

• LG TVs: Look for “Sound Out” settings that allow “Optical + Internal TV Speaker” or “Wired Headphones + TV Speaker.”
• Samsung TVs: Check the Accessibility menu for “Multi-output Audio.” This keeps the TV speakers active while also sending audio to Bluetooth headphones.
• Roku: The Private Listening feature via the Roku app cuts TV audio by default, but some settings allow you to mix audio depending on the OS version.

Connecting Computer Speakers (USB Powered)

If you have a pair of small PC speakers, they likely have a 3.5mm plug for sound and a USB cable for power. You can use these with a TV.

1. Plug in audio — Connect the green 3.5mm jack to the TV’s headphone port.
2. Plug in power — Insert the USB connector into any available USB port on the TV. Most TV USB ports provide enough power (5V) to run small computer speakers.
3. Check power settings — Note that when you turn the TV off, the USB port usually powers down, turning off the speakers automatically.

Using A Receiver Or Amplifier

Passive speakers (speakers without a power cord) cannot plug directly into a TV. They need an amplifier to drive them. In this case, your TV connects to the receiver, and the receiver connects to the speakers via speaker wire.

This is the standard layout for home theater systems. You run an HDMI or Optical cable from the TV to the receiver’s input (often labeled “TV Audio”). Then, you strip the plastic off the ends of your speaker wire and clamp them into the binding posts on the back of the receiver. This setup offers the best possible audio fidelity and allows for true 5.1 or 7.1 surround sound configurations.
