How to connect speakers to a TV (2026)
Quick Answer
To connect speakers to a TV, first identify what audio outputs your TV has, then match that to the type of speakers you own: HDMI ARC/eARC and optical are the most common and reliable choices. Powered speakers and soundbars can usually connect directly; passive speakers normally need an amplifier or AV receiver between the TV and the speakers. After connecting, change the TV’s sound output settings so audio is sent to the external speakers instead of the built-in TV speakers.
Overview
Connecting speakers to a TV is usually straightforward once you know two things: what kind of audio output the TV provides, and whether your speakers are powered or passive. Powered speakers, soundbars and many wireless speaker systems have their own amplification, so they can often connect directly by HDMI ARC/eARC, optical, analogue audio output or Bluetooth if the TV supports it. Passive speakers do not power themselves, so they need an amplifier or AV receiver in the middle. The best connection for most people is HDMI ARC or eARC because it can send TV sound to external speakers through one cable and often lets the TV remote control volume. Optical is a strong fallback when HDMI ARC is not available. Analogue headphone or line-out can work with some powered speakers, but sound quality and volume control can vary. Bluetooth is convenient but may introduce delay or reduce sound quality depending on the devices. The key to avoiding frustration is to check the ports before buying cables, power everything off before plugging in, and then select the correct audio output in the TV’s settings. If there is no sound after connecting, the problem is usually the wrong input on the speakers, the wrong output selected on the TV, or a mismatch between passive and powered equipment.
Who this is for
Anyone setting up a TV with a soundbar, powered speakers, a wireless speaker system, or an amplifier/AV receiver and passive speakers.
What you’ll need
- TV with an available audio output such as HDMI ARC/eARC, optical, analogue audio out or Bluetooth support
- Speakers, soundbar, amplifier or AV receiver that matches the TV’s output
- Correct cable for your setup, such as HDMI, optical or analogue audio cable
- Mains power for any powered speakers, soundbar, amplifier or receiver
- TV and speaker manuals or the manufacturer setup pages
Before you start
Check whether your speakers are powered or passive. Powered speakers and soundbars can usually connect directly to the TV; passive speakers need an amplifier or AV receiver. Also check the exact labels on the TV ports, such as HDMI ARC, HDMI eARC, Optical, Digital Audio Out, Headphone or Audio Out, because using the wrong port is a common cause of no sound.
Step-by-step
- 1
Identify the TV audio output and speaker input
Look at the back or side of the TV and the inputs on your speakers, soundbar, amplifier or receiver. Match the best common connection they both support. Prioritise HDMI ARC or eARC if both devices have it. If not, look for optical. Use analogue output only if both devices support it. Use Bluetooth only if you want a wireless connection and both devices support TV audio over Bluetooth.
Why: This decides whether the connection will work at all and affects sound quality, convenience and volume control.

Choose the right connection method for your setup
If you have a soundbar or powered speakers with HDMI ARC/eARC, use that. If your TV and audio device both have optical, use an optical cable as the next best common option. If you have passive speakers, connect the TV to an amplifier or AV receiver first, then connect the speakers to that equipment according to its manual. If using a headphone or analogue audio out, connect only to speakers or equipment designed to accept that signal.
Why: Different speakers need different signal types. Passive speakers cannot safely or properly run from a TV audio output alone.
- 3
Power off the equipment before making connections
Turn off the TV and unplug or switch off the speakers, soundbar, amplifier or receiver before connecting cables. Then attach the cable firmly to the correct labelled ports. If using HDMI, make sure it is in the ARC or eARC port on the TV and the matching port on the audio device.
Why: This reduces the risk of connection errors and helps the devices recognise the link cleanly when powered back on.
- 4
Connect and power the speakers correctly
If using powered speakers or a soundbar, connect their power cable and switch them on. If using passive speakers with an amplifier or receiver, make sure the speakers are connected to the amplifier or receiver outputs exactly as shown in that product’s manual, then power on the amplifier or receiver.
Why: External speakers must be powered or driven by an amplifier. A correct physical connection is essential before any TV settings can work.
- 5
Select the correct input on the speakers or audio system
Use the speaker, soundbar, amplifier or receiver remote or control panel to choose the input that matches the cable you connected, such as TV, ARC, HDMI, Optical or Line In.
Why: Even a correct cable connection will produce no sound if the audio device is listening to the wrong input.
- 6
Change the TV audio output settings
Open the TV sound settings and switch the audio output from the internal TV speakers to the external audio device. If using HDMI ARC/eARC, you may also need to enable the TV’s HDMI control feature. If using optical, choose the digital audio output option that your audio device supports, following both manuals if there are format choices.
Why: The TV must be told where to send sound. This step is often what makes the system start working.
- 7
Test sound and adjust volume behaviour
Play a TV channel, streaming app or built-in test sound if available. Raise the volume gradually. Check whether the TV remote controls the speaker volume directly or whether you must use the audio device remote. If the sound is delayed on Bluetooth or some digital setups, look for audio delay or lip-sync settings on the TV or audio device.
Why: Testing confirms both signal and control are working, and helps you fix common issues such as silence, distortion or lip-sync problems straight away.
Why this works
A TV outputs audio in a small number of standard formats and connection types. When the TV’s output matches an input your speaker system can decode or amplify, the signal can be reproduced as sound. HDMI ARC/eARC and optical carry digital audio, while analogue outputs carry an already-converted audio signal suitable for compatible powered equipment.
Common mistakes to avoid
- Trying to connect passive speakers directly to the TV without an amplifier or AV receiver
- Plugging an HDMI cable into a normal HDMI port instead of the ARC or eARC-labelled port
- Leaving the TV set to its internal speakers after connecting external audio
- Selecting the wrong input on the soundbar, speakers, amplifier or receiver
- Assuming every TV supports Bluetooth audio output
- Using an output and input that do not match, such as a digital TV output into speakers that only accept analogue audio
Troubleshooting
No sound from the speakers
Check that the cable is in the correct ports, the speakers or audio system are powered on, the correct input is selected on the audio device, and the TV audio output is set to external speakers.
TV remote does not control volume
If using HDMI ARC/eARC, enable the TV’s HDMI control feature and the matching control feature on the audio device. With optical or some analogue connections, you may need to use the speaker or soundbar remote instead.
Sound is delayed or lip-sync is off
Use the TV or audio device lip-sync or audio delay setting. If you are using Bluetooth, try a wired connection instead for more stable timing.
Sound is distorted or too quiet
Make sure you are using the correct type of output for the speakers, reduce any overly high output level if the device allows it, and check that analogue connections are going into a compatible input such as Line In rather than an unsuitable port.
Works on one app or source but not another
Check the TV’s digital audio format settings and the supported formats listed in your speaker, soundbar or receiver manual. Some equipment may need a different output format setting.

Alternatives
- Use a soundbar instead of separate speakers for a simpler TV audio upgrade
- Use an AV receiver if you want to connect multiple devices and passive speakers
- Use a streaming device or set-top box audio output if your TV lacks a suitable output and your equipment supports the source device connection
Pro tips
- Take a photo of the TV ports before buying cables or speakers so you can match the labels accurately
- If both HDMI ARC/eARC and optical are available, try HDMI first for easier control and fewer remotes
- Label the cable ends if your TV is wall-mounted, so future troubleshooting is easier
- Keep the speaker manual nearby during setup because input names vary by brand
Safety notes
- Power off equipment before connecting or disconnecting cables
- Do not force plugs into ports; if it does not fit easily, recheck the port type and orientation
- Keep cables tidy and away from walkways to reduce trip hazards
- Use only the power supplies and mains leads specified by the equipment manufacturer

Cost considerations
The cheapest route is often using existing powered speakers with a compatible cable. Passive speakers usually cost more to set up with a TV because they need an amplifier or AV receiver as well as speaker cable and possibly a TV audio cable.
Frequently asked questions
Can I connect normal hi-fi speakers straight to my TV?+
Only if they are powered speakers with their own built-in amplification and a compatible input. Passive hi-fi speakers need an amplifier or AV receiver.
Which connection gives the best result for most people?+
HDMI ARC or eARC is usually the best balance of sound quality, convenience and remote control integration when both the TV and audio device support it.
Can I use Bluetooth speakers with my TV?+
Sometimes. The TV must support Bluetooth audio output, and the speakers must support pairing in a compatible way. Be aware that Bluetooth can introduce audio delay.
Why is there no sound even though the cable is connected?+
The most common reasons are the wrong TV audio output setting, the wrong input selected on the speakers or soundbar, using the wrong physical port, or trying to use passive speakers without an amplifier.
Do I need to turn off the TV’s built-in speakers?+
Usually the TV does this automatically when you choose an external audio output, but some TVs need you to select external speakers manually in the sound settings.
