How to Connect an AV Receiver to a TV
If you want better sound, cleaner cable management, and a more flexible home theater setup, learning how to connect an AV receiver to a TV is the first step.
The process is simple once you understand which HDMI ports to use, how audio return works, and what settings need to be changed on both devices.
This guide explains the connections, setup options, and common mistakes that can affect picture or sound quality.
You will also learn how HDMI ARC, eARC, optical audio, and legacy connections fit into a modern AV receiver and television system.
What an AV Receiver Does
An AV receiver acts as the central hub for audio and video in a home entertainment system.
It takes input from devices such as a streaming box, Blu-ray player, game console, or media player, then sends video to the TV and sound to connected speakers.
Most modern receivers support surround sound formats like Dolby Digital, Dolby Atmos, DTS, and PCM audio.
Many also include HDMI switching, room calibration, network streaming, and support for 4K or 8K video passthrough.
What You Need Before You Start
Before connecting anything, confirm the ports available on your TV and AV receiver.
The exact setup depends on whether your equipment supports HDMI ARC, eARC, or only standard HDMI and optical audio.
- An AV receiver with HDMI output
- A TV with HDMI ARC or eARC if possible
- High-speed HDMI cables rated for your resolution and refresh rate
- Optional optical cable for older gear
- Speaker wire and speakers already connected to the receiver
Check your TV manual and receiver manual for port labels.
Manufacturers often use similar terms, but the placement and features can differ between LG, Samsung, Sony, TCL, Panasonic, Denon, Yamaha, Onkyo, and Marantz models.
How to Connect AV Receiver to TV Using HDMI
HDMI is the preferred method because it carries both video and audio through a single cable.
In most systems, the receiver sends video to the TV while the TV displays the image and the receiver handles sound.
- Locate the HDMI output on the AV receiver, usually labeled HDMI OUT or Monitor Out.
- Connect one end of the HDMI cable to that output.
- Connect the other end to an HDMI input on the TV.
- Power on the TV and receiver.
- Select the correct HDMI input on the TV.
For the best results, use the TV port labeled ARC or eARC if your goal is to send TV audio back to the receiver.
If the TV and receiver both support eARC, you can often pass higher-quality audio formats than standard ARC allows.
What Is HDMI ARC and eARC?
HDMI ARC means Audio Return Channel.
It allows the TV to send audio back to the receiver through the same HDMI cable used for video.
This is useful when you stream from apps built into the TV, such as Netflix, Disney+, Hulu, Apple TV+, or YouTube.
eARC stands for Enhanced Audio Return Channel.
It offers more bandwidth and better support for lossless formats such as Dolby TrueHD and uncompressed PCM, depending on the devices involved.
If you own a soundbar alternative setup with a full receiver and speaker system, eARC is usually the better long-term option.
When should you use ARC or eARC?
Use ARC or eARC when you want audio from the TV’s built-in apps or antenna channels to play through the AV receiver.
Without ARC, you may need a second connection like optical audio for TV sound.
Make sure both devices have ARC or eARC enabled in their settings.
On many TVs, the feature is turned off by default.
How to Set Up TV Audio Return
After the cables are connected, adjust the settings so the TV can send sound to the receiver.
- On the TV, enable HDMI ARC or eARC in the sound or external device menu.
- On the receiver, select the correct input mode for TV audio, often labeled TV Audio, ARC, or eARC.
- Set the TV speakers to external speakers or audio system.
- Confirm that HDMI-CEC is enabled if required by your devices.
HDMI-CEC may appear under names such as Anynet+ on Samsung, Bravia Sync on Sony, Simplink on LG, or VIERA Link on Panasonic.
It allows the TV and receiver to communicate more easily, including power and volume control.
How to Connect Without HDMI ARC
If your TV does not support ARC or your receiver is older, you can still connect the devices with HDMI for video and optical audio for sound.
This is a reliable fallback for many households.
- Connect the receiver’s HDMI output to the TV.
- Connect an optical digital audio cable from the TV’s optical output to the receiver’s optical input.
- Change the TV’s audio output setting to optical or external audio system.
- Select the matching input on the receiver.
Optical audio supports compressed surround formats such as Dolby Digital, but it does not support the full bandwidth of eARC.
If you use a streaming service or console that outputs advanced audio, HDMI ARC or eARC is usually preferable.
Connecting Source Devices Through the Receiver
For the cleanest setup, connect your source devices directly to the AV receiver rather than the TV.
This allows the receiver to manage switching and surround decoding.
- HDMI from game console to receiver input
- HDMI from Blu-ray player to receiver input
- HDMI from streaming device to receiver input
- Receiver HDMI output to TV HDMI input
This arrangement is especially useful for PlayStation, Xbox, Apple TV, Roku, Fire TV Stick, and Ultra HD Blu-ray players.
It can also reduce input lag if your receiver supports modern passthrough standards.
Common Problems and How to Fix Them
Even simple connections can fail if one setting is wrong.
The most common issues involve the wrong HDMI port, disabled CEC control, or incompatible audio settings.
No sound from the TV to the receiver?
Check that the TV audio output is set to external speakers or HDMI ARC/eARC.
Also verify that the receiver is on the correct input and that the HDMI cable is plugged into the ARC-capable port on both devices.
Picture works but sound does not?
Confirm that the receiver supports the audio format being sent by the TV.
If the TV is outputting Dolby Atmos through streaming apps, the receiver must support it through ARC or eARC.
Otherwise, switch the TV to PCM or standard Dolby Digital.
The TV and receiver do not turn on together?
Enable HDMI-CEC on both devices.
If the brands use different names for CEC, look for the equivalent control setting in each menu.
Remote volume control is not working?
CEC or IR learning may need to be activated in the receiver.
Some remotes also require a setup code or pairing step before the TV can adjust receiver volume.
Best Practices for Better Performance
A few setup habits can improve reliability and simplify daily use.
These are especially helpful in systems with multiple HDMI sources or a 4K HDR television.
- Use certified HDMI cables for 4K, 120Hz, HDR, or 8K systems
- Keep cable runs as short as practical
- Update TV and receiver firmware if audio or video behavior is unstable
- Match the receiver output resolution to the TV’s native capabilities
- Run room calibration if your receiver includes auto setup software
If your receiver supports Dolby Vision, HDR10, HLG, or passthrough for 120Hz gaming, check that those features are enabled for the correct input.
Some receivers require per-input configuration.
Should You Connect the TV to the Receiver or the Receiver to the TV?
In most home theater setups, the receiver connects to the TV through its HDMI output, while all source devices connect to the receiver.
This gives the receiver control over switching, audio decoding, and speaker output.
If you only use the TV’s built-in apps and do not connect external devices, the receiver still connects to the TV through ARC or eARC so the TV can send audio back to the receiver.
This is the most common answer to how to connect av receiver to tv in a modern setup.
When an Optical Cable Still Makes Sense
Optical audio remains useful for older TVs, legacy receivers, and setups where ARC is unreliable.
It is also a good temporary solution if you are troubleshooting HDMI handshakes or CEC conflicts.
However, optical has limits.
It cannot carry the same high-bitrate formats as HDMI eARC, and it does not support the same level of device communication.
For new installations, HDMI should be the first choice whenever possible.
Final Setup Check
After connecting everything, test each input one by one.
Confirm that the TV displays video correctly, the receiver plays audio from both external devices and TV apps, and remote control functions behave as expected.
If the setup includes a sound system with a subwoofer, center channel, or surround speakers, make sure the receiver’s speaker configuration matches the actual room layout.
That final check helps you get the most from the connection and ensures your home theater works the way it should.
