Quick Answer / Summary: To use HDMI ARC, connect the TV’s ARC or eARC port to the soundbar or receiver’s ARC or eARC input, enable HDMI-CEC on both devices, and set the TV’s digital audio output to the receiver or ARC with the format on Auto or Bitstream. Then test with the TV’s own app audio, not a source behind the receiver, because only audio produced inside the display uses the return.
Setting up ARC is a short sequence rather than a project: one cable into the right sockets, two settings that enable the handshake, and a test that uses the one kind of audio only the return can carry. Following the sequence in order matters, because a fault in an early step makes later tests meaningless and sends people looking for problems in the wrong place.
How to Use HDMI ARC: Setup Steps, Settings and Checks
Step One: Wire the Right Ports
Identify the ARC port on the television – the socket labelled ARC, HDMI ARC or eARC – and the matching input on the audio device, labelled TV, TV (ARC), ARC or eARC. Connect them with a single HDMI cable rated for the video on the leg: High Speed or Premium High Speed for 4K60, Ultra High Speed where 4K120 or 8K video is involved.
Leave the sources where they are. If they are on the receiver, nothing changes; if they are on the television, only the return needs wiring. The single most common setup error is putting the cable in a convenient plain HDMI input instead of the marked ARC port, so this step is worth checking twice.
Step Two: Enable the Handshake
Turn on HDMI-CEC on both devices. The feature hides under brand names: Anynet+ on some televisions, Bravia Sync, Simplink, Viera Link or simply HDMI Control on others, and often a separate toggle on soundbars and receivers. ARC is negotiated over that control channel, so without it the return never activates.
The brand names HDMI-CEC hides behind
If CEC has been disabled to stop unwanted input switching, look for the individual options such as auto input switching or one-touch play and disable only those. That keeps the handshake alive while removing the behaviour that prompted the change.
Step Three: Point the Audio at the Right Output
In the television’s sound settings, choose the receiver, audio system or ARC as the output instead of the TV speakers, and set the digital format to Auto or Bitstream so compressed surround audio survives the trip. PCM is appropriate only when the audio device cannot decode the source format. On an eARC leg, pass-through is the setting that preserves the original stream rather than a downmix.
On the soundbar or receiver, select the ARC or TV input once. The handshake handles switching afterwards, and the television’s own remote should then adjust the volume of the external device.
Step Four: Test, Then Diagnose in Order
Test with the television’s own audio: open a streaming app on the panel and listen. If the sound arrives and the volume responds to the television’s remote, the return is working. If it does not, work through four checks in sequence – port labels, CEC status, audio output setting, then volume behaviour – because each one depends on the previous.
The four checks in dependency order
Two further symptoms point to specific stages. Audio that works until a source behind the receiver is selected is not an ARC fault at all, since those sources never use the return. Audio that arrives but in a downgraded format points to the return standard or the pass-through setting rather than to the cable.
ARC Setup Sequence and Checks
| Step | Action | Confirmation |
|---|---|---|
| 1 | Cable from the TV’s ARC port to the device’s ARC input | Both ends on marked sockets, cable rated for the video |
| 2 | Enable HDMI-CEC on both devices | Volume control from the TV remote reaches the device |
| 3 | Set the TV audio output to receiver or ARC | TV speakers fall silent when external audio is selected |
| 4 | Set the format to Auto, Bitstream or pass-through | Receiver reports surround rather than stereo PCM |
| 5 | Test with the TV’s own app audio | Sound plays through the external device |
| 6 | Test a lossless source for eARC | Receiver reports TrueHD, DTS-HD MA or multichannel PCM |
| 7 | If silent, recheck ports, CEC, output setting in that order | Fault isolated to one stage rather than the whole chain |
Real-World Application Scenarios
The sequence works the same way in every room. A living-room setup with a soundbar takes minutes and finishes with one remote controlling volume. A receiver-based cinema uses the same steps but tests with the television’s apps, since the receiver already handles the disc player. A guest room with a small bar follows the identical process, which is what makes it teachable to staff. Where a display has no return port, the same test sequence applies to the extractor that replaces it, with the extractor’s output feeding the amplifier.

Frequently Asked Questions (FAQ)
Q: What is the correct order to set up HDMI ARC?
A: Wire the ARC ports first, enable HDMI-CEC on both devices second, set the television’s audio output to the receiver or ARC third, and test with the television’s own app audio. Diagnosing in that same order isolates a fault to a single stage.
Q: Why do I need to test with the TV’s apps rather than my cable box?
A: Because the ARC return only carries audio produced inside the television. A set-top box, console or disc player connected behind the receiver sends its audio through the receiver and never uses the return, so it cannot confirm whether ARC is working.
Q: Do I need to change any settings on the soundbar?
A: Usually just select the ARC or TV input once. Some bars also have a CEC or auto-power option that should stay enabled so the handshake completes and the bar wakes with the television.
Q: What should I check first if the sound never arrives?
A: The port labels on both devices. A cable in a plain HDMI input instead of the ARC socket is the single most common cause, followed by HDMI-CEC being switched off and the television’s audio output still pointed at its internal speakers.
