How to connect an AV receiver with HDMI
If you want better sound from your TV, streaming apps, or game console, HDMI is the simplest way to connect an AV receiver.
The catch is that a few cable choices and menu settings determine whether you get basic audio, full surround sound, or advanced features like ARC and eARC.
This guide explains how to connect an AV receiver with HDMI, what each port does, and how to avoid the setup mistakes that cause silent speakers or missing video.
What you need before you start
Before connecting anything, identify the devices in your system and check their HDMI capabilities.
A modern home theater setup usually includes a television, AV receiver, and one or more source devices such as a Blu-ray player, game console, Apple TV, Roku, Fire TV, or cable box.
- AV receiver with HDMI inputs and at least one HDMI output
- TV with an HDMI input, ideally one labeled ARC or eARC
- High-Speed or Ultra High Speed HDMI cables
- Source devices such as streaming boxes, consoles, or disc players
Check the back panel and look for labels such as HDMI IN, HDMI OUT, ARC, and eARC.
These labels matter because they determine where each cable goes and whether your TV can send audio back to the receiver.
Basic HDMI wiring for an AV receiver
The most common setup is simple: connect your devices to the receiver, then send one cable from the receiver to the TV.
In this arrangement, the AV receiver acts as the hub for both audio and video.
- Connect each source device to an HDMI IN port on the AV receiver.
- Connect the receiver’s HDMI OUT port to an HDMI input on the TV.
- Select the correct HDMI input on the TV.
- Select the matching source on the receiver.
This setup works well because the receiver can decode audio formats such as Dolby Digital, DTS, Dolby TrueHD, and Dolby Atmos, depending on the equipment and content.
It also reduces cable clutter because all sources run to the receiver instead of directly to the TV.
How HDMI ARC and eARC change the connection
ARC stands for Audio Return Channel, and eARC stands for Enhanced Audio Return Channel.
These features let your TV send sound back to the AV receiver through the same HDMI cable used for video output.
ARC is useful when you use the TV’s built-in apps, such as Netflix, Hulu, Disney+, or YouTube, because the audio from those apps can play through your receiver and speakers. eARC offers higher bandwidth and better support for uncompressed audio formats, which is important for lossless surround sound and object-based formats like Dolby Atmos in supported setups.
When should you use ARC or eARC?
- Use ARC if your TV and receiver support it and you want simple audio return from smart TV apps.
- Use eARC if both devices support it and you want broader compatibility with high-quality audio formats.
- Use the standard receiver-to-TV HDMI connection if all source devices connect to the receiver and you do not need TV app audio.
For ARC or eARC to work, both the TV and receiver must support the feature, and the cable must be connected to the correct HDMI ports labeled ARC or eARC.
How to connect the TV to the receiver
If your goal is to route all audio through the receiver, the TV-to-receiver HDMI connection is usually the most important part of the system.
Use the receiver’s HDMI output and connect it to the TV’s ARC or eARC port if available.
If not, any available HDMI input on the TV can carry video from the receiver.
On many TVs, the ARC/eARC port is HDMI 2 or HDMI 3, but the port number varies by brand.
Always check the labeling near the port or in the user manual.
Common TV brands such as Samsung, LG, Sony, TCL, Hisense, and Panasonic often use similar naming conventions, but the location differs.
How to connect source devices to the AV receiver
For the cleanest setup, connect each source device directly to the receiver.
This lets the receiver manage switching and audio decoding.
- Game console: Connect to a receiver HDMI input that supports 4K, 120Hz, or VRR if you use a PlayStation 5 or Xbox Series X.
- Streaming device: Connect to any available HDMI input, then use the receiver to switch sources.
- Blu-ray player: Connect to an HDMI input that supports full-bandwidth video and audio.
- Cable or satellite box: Connect directly to the receiver if you want all TV audio through the speakers.
If your receiver has HDMI 2.1 features, verify that the specific input supports them.
Some receivers only include full 8K or 4K/120 passthrough on certain ports.
How to set up HDMI output on the receiver and TV
After wiring the system, the next step is adjusting the settings.
This is where many HDMI setups fail even though the cables are correct.
Receiver settings to check
- HDMI Control: Enable if you want ARC, eARC, or one-touch power and volume control.
- ARC/eARC: Turn on if you use the TV’s internal apps or need audio return.
- Input assignment: Make sure the HDMI input matches the source device.
- Video output: Set to auto or passthrough if available.
TV settings to check
- Speaker output: Choose external speakers, audio system, or receiver.
- CEC: Enable HDMI-CEC if required for ARC/eARC.
- Digital audio format: Select auto, passthrough, or bitstream when available.
- ARC/eARC: Turn on in the sound menu if supported.
Different brands use different names for HDMI-CEC.
Examples include Anynet+ on Samsung, Simplink on LG, Bravia Sync on Sony, and VIERA Link on Panasonic.
Common HDMI formats and what they mean
Understanding HDMI versions helps you avoid mismatched expectations.
HDMI 1.4 introduced ARC, while HDMI 2.1 added support for higher bandwidth features such as 4K at 120Hz, variable refresh rate, and eARC.
- HDMI ARC: Audio return for compressed and some enhanced audio formats
- HDMI eARC: Higher bandwidth audio return for advanced formats
- HDMI 2.0: Common for 4K HDR playback at up to 60Hz
- HDMI 2.1: Required for many modern gaming and 8K features
For most home theater users, a certified High-Speed HDMI cable is enough for 1080p and 4K at 60Hz, while Ultra High Speed HDMI cables are better suited for HDMI 2.1 features.
Troubleshooting HDMI connection problems
If your receiver is connected but you still do not get sound or picture, the problem is usually one of four things: the wrong port, an incorrect menu setting, a poor cable, or a device compatibility issue.
Why is there no sound from the speakers?
- Confirm the receiver is set to the correct input.
- Check that TV audio output is set to external speakers or audio system.
- Make sure ARC or eARC is enabled on both devices.
- Verify HDMI-CEC is enabled if the setup requires it.
Why is there no picture on the TV?
- Check that the receiver’s HDMI output goes to the TV’s active HDMI input.
- Test the HDMI cable with another device.
- Switch the TV input manually instead of relying on auto-detect.
- Confirm the receiver supports the resolution or refresh rate you are using.
Why do the TV speakers still play sound?
- Change the TV audio output to receiver, external audio system, or home theater.
- Disable internal speakers if the menu offers that option.
- Restart the TV and receiver after changing ARC or CEC settings.
Best practices for a reliable HDMI setup
Good cable management and consistent settings make a noticeable difference in daily use.
Use short, certified HDMI cables when possible, avoid unnecessary adapters, and label your source inputs so switching is easier later.
- Keep HDMI cables as short as practical for the room layout.
- Use certified cables for 4K, HDR, or HDMI 2.1 setups.
- Update the receiver and TV firmware if you encounter handshake issues.
- Power on the TV and receiver after making major wiring changes.
- Use the receiver manual to verify which HDMI inputs support advanced features.
For mixed systems, such as older speakers with a newer TV or a modern console with an older receiver, compatibility planning matters.
A newer source may output a signal that the receiver can pass only if it supports the same resolution, refresh rate, and audio format.
When to use HDMI splitters, switches, or adapters
Most home theater systems do not need extra hardware, but some setups require a splitter or switch.
Use these only when the receiver lacks enough HDMI inputs or when you need to send video to more than one display.
Adapters can solve niche problems, but they can also introduce handshake failures, audio limitations, or reduced video quality.
If possible, connect source devices directly to the receiver rather than relying on extra HDMI accessories.
What to remember about connecting an AV receiver with HDMI
The cleanest setup is usually source devices into the AV receiver, then one HDMI cable from the receiver to the TV.
If you want audio from smart TV apps, use ARC or eARC and make sure HDMI-CEC is enabled on both devices.
Once the ports and settings are correct, HDMI gives you a simple way to manage video, surround sound, and modern features from a single hub.
