Check the exact HDMI port labels on both devices, then confirm the TV and soundbar model manuals. A TV may have several HDMI sockets while only one supports Audio Return Channel (ARC) or enhanced Audio Return Channel (eARC). To use eARC, the TV and soundbar must both support eARC, and the source, content and settings must support the audio format you want. If either device is ARC-only, the connection is limited to ARC capabilities.
The compatibility rule that prevents most soundbar mistakes
A soundbar feature is available only when the entire signal path supports it. That path includes the TV port, the soundbar’s TV-facing port, the HDMI cable, the source device, the content and relevant settings. The word HDMI on a socket is not enough: look specifically for ARC or eARC beside the port and in the model documentation.
- ARC: sends TV audio back to a soundbar over HDMI and can support HDMI-linked functions such as TV-remote volume and power behavior.
- eARC: provides greater bandwidth than ARC and supports additional high-bitrate formats, but both connected devices must support eARC.
- Optical: can carry TV audio when ARC/eARC is unavailable, but it does not provide HDMI-dependent functions such as power interlock and TV-remote volume control. Format support depends on the specific models.
Use the following comparison as a decision aid, then verify every row against the manuals for your particular TV and soundbar.
| Connection | TV requirement | Soundbar requirement | What it can provide | Important limitation |
|---|---|---|---|---|
| eARC | HDMI port identified as eARC | TV-facing HDMI output identified as eARC | TV audio over HDMI with higher bandwidth and support for additional high-bitrate formats | Both ends, the source, the content and settings must support the desired format |
| ARC | HDMI port identified as ARC | TV-facing HDMI output identified as ARC | TV audio over one HDMI cable and possible HDMI-linked control functions | The link is limited to ARC specifications, even if another device in the chain supports eARC |
| Optical | Optical digital-audio output | Optical digital-audio input | A fallback digital-audio connection from the TV | No HDMI power interlock or TV-remote volume control; exact audio formats are model-specific |
Sony publishes eARC data transfer of up to 37 Mbs. That is a manufacturer technical figure, not an independent measurement; the practical result still depends on the connected devices and content. See Sony’s eARC explanation.

1. Find the exact TV and soundbar model numbers
Write down the complete model number from the TV’s rear label, settings screen or original documentation. Do the same for the soundbar. A product family can contain models with different ports, regional variants and firmware behavior, so a search for a series name alone is not sufficient.
Where to look on the TV
- Open the TV’s system-information or support screen and copy the full model designation.
- Check the rear or side label if the software menu omits a suffix.
- Record the purchase region when the manufacturer lists separate regional specifications.
Where to look on the soundbar
- Check the label on the soundbar, its packaging or its settings display.
- Confirm whether the connector is labeled HDMI OUT (TV ARC), HDMI OUT (eARC) or with equivalent wording. An HDMI input for a console or disc player is not the same as the TV-facing output.
- Note whether an optical input is present, even if you plan to use HDMI; it determines whether you have a fallback.
2. Inspect the physical HDMI labels
With the devices switched off or in standby, inspect each HDMI socket. Find the TV socket marked ARC or eARC and plan to use that exact port. Do not assume that HDMI 1, HDMI 2 or every socket on the set supports audio return. Sony specifically warns that a TV can have multiple HDMI ports without ARC/eARC on all of them; its soundbar connection guide shows why the labeled port matters.
On the soundbar, identify the connector intended for the television. A port labeled HDMI IN accepts a source device; it does not normally send the TV’s audio back. Use the output marked for TV ARC/eARC. If the bar has several outputs or an HDMI input, read the manual to determine which one carries return audio.

3. Read the TV manual for audio-return and pass-through details
Open the support page for the exact TV model and read the connection diagram, specifications and audio-settings sections. Look for:
- The HDMI socket assigned to ARC or eARC.
- Whether eARC is enabled automatically or requires an eARC, HDMI-control or digital-audio setting.
- Digital-audio output choices such as PCM, Auto, Pass-through or Bitstream, using the labels supplied for that model.
- Which formats the TV can pass from built-in streaming apps and from devices connected to the TV’s other HDMI inputs.
Do not treat a general product description that says “eARC” as proof that every source will deliver a particular format. A TV’s built-in apps and an external player can use different signal paths. Sony’s BRAVIA connection instructions illustrate why the routing diagram and port assignment must be checked for the exact model.
4. Read the soundbar manual for the feature you actually want
Confirm the soundbar’s TV-facing HDMI output specification, not just the presence of an HDMI connector. The manual should state whether that output supports ARC, eARC or both, and list the audio formats accepted through it.

If you want Dolby Atmos or another high-bitrate format
Check four things together: the soundbar’s decoder, the TV’s pass-through capability, the source device’s output settings and the content’s soundtrack. eARC can carry additional high-bitrate formats, including uncompressed 5.1/7.1, Dolby Atmos, DTS:X, DTS-HD Master Audio and Dolby TrueHD according to Sony’s eARC documentation, but an eARC label by itself does not guarantee that a specific app, disc or game will output one of them. The Sony Dolby Atmos connection guide describes the source and routing conditions that also need to be met.
If you want one-remote control
ARC/eARC can carry HDMI control signals that allow compatible equipment to coordinate power and volume. Verify that the TV and soundbar both support the relevant HDMI-control feature and that it can be enabled in their settings. An optical-only connection cannot provide those HDMI-dependent functions.
5. Decide whether ARC is enough or eARC is necessary
Choose the connection based on the capability you need, not on the newest label.
- Choose eARC when both devices support it and you need the higher-bandwidth formats listed in their manuals, or when you want the broadest format headroom for compatible sources.
- Choose ARC when the TV and soundbar are ARC-compatible and the formats listed for your content fit within ARC specifications. An eARC TV connected to an ARC-only soundbar still operates only within ARC capability.
- Choose optical as a fallback when neither device offers usable ARC/eARC, or when the manuals show that optical meets your format needs and you do not require HDMI-linked power or volume behavior.
ARC and eARC are not interchangeable in capability. Sony describes ARC as connecting the TV and audio system with one High Speed HDMI cable and eliminating the need for a separate composite or optical cable; see Sony’s ARC explanation. eARC is the higher-bandwidth version, but it works only when both ends support eARC.
6. Build the connection correctly
- Identify the ports. Locate the TV’s HDMI ARC/eARC socket and the soundbar’s TV-facing HDMI ARC/eARC output. Do not substitute another TV HDMI socket merely because it is closer or easier to reach.
- Check the cable guidance. Sony recommends a High Speed HDMI cable with Ethernet for eARC data transfer. Some external-device and high-quality-format configurations call for a higher-bandwidth cable class, so follow the cable specification in the particular TV, soundbar and source manuals. A cable cannot create ARC or eARC functionality that the hardware lacks.
- Connect the TV and soundbar. Plug one end into the labeled TV port and the other into the labeled soundbar output. If you are using an external player through the soundbar, connect that player to the soundbar’s HDMI input only when the manual says the input accepts the format you need.
- Set the TV’s audio output. In the TV’s sound or audio menu, select the external audio system, receiver or HDMI ARC/eARC output option provided by that model. Set digital-audio output or pass-through according to the format instructions in the manuals.
- Enable the required control and eARC options. If the TV or soundbar has separate HDMI-control, ARC or eARC toggles, enable the options required by the manufacturers. Names and menu locations vary by model.
- Configure the source. On a disc player, console or streaming device, choose the output mode recommended for the soundbar and TV. Confirm that the title, game or stream actually contains the format you are testing.
- Test a known signal. Start with ordinary TV audio, then test the higher-format source. Check the soundbar’s information display or manual-defined indicator rather than assuming that a single logo on the product box proves the current signal.
Will an external player solve a TV eARC limitation?
Sometimes. If the soundbar has an HDMI input, you can connect a Blu-ray player or game console directly to that input and send audio to the soundbar before the video continues to the TV. This arrangement can enable higher-quality audio even when the TV does not have eARC, provided the source, soundbar input and cable support the required format. Sony documents this type of routing in its Dolby Atmos guidance.
There are trade-offs. The soundbar must accept the video signal and pass it to the TV, and the TV may not receive every system sound from the source. A console’s menu sounds, notification tones or other TV-generated audio can follow a different path from the disc or game soundtrack. Read the soundbar’s HDMI-input and pass-through specifications before choosing this layout.

Optical fallback: what you gain and lose
Use optical only after checking that the TV has an optical digital-audio output and the soundbar has an optical input. Optical can restore TV sound when ARC/eARC is absent or unusable, and Sony lists it as an alternative connection in its support material.
- Optical does not carry the HDMI control functions used for power interlock and TV-remote volume control.
- The formats available over optical depend on the exact TV and soundbar; consult both manuals rather than assuming that every soundtrack will pass.
- You may need to control volume from the soundbar remote or use another supported control method.
How to diagnose a failed or downgraded connection
No sound over HDMI
- Recheck that the cable is in the TV’s port labeled ARC/eARC and the soundbar’s TV-facing HDMI output.
- Verify in both manuals that the selected ports support the same return-channel feature.
- Review the TV’s audio-output selection and any separate ARC, eARC or HDMI-control settings.
- Try the cable class specified by the manufacturers, especially when eARC is required.
Sound works, but the expected format does not appear
- Confirm that both devices support the format, not merely that one of them has eARC.
- Check the source output mode, the TV’s pass-through setting and the soundtrack or stream itself.
- Determine whether the signal comes from a built-in TV app or an external player; those routes can have different capabilities.
Volume or power control is missing
If the connection is optical, the missing HDMI-linked behavior is expected. To obtain one-remote volume or power operation, verify that both devices support the relevant HDMI-control functions and connect through compatible ARC/eARC ports.
An external player works but TV apps do not, or the reverse
Trace each signal path separately. A player connected directly to the soundbar uses the bar’s HDMI input, while a built-in app sends audio from the TV through ARC/eARC or optical. Compare the format and pass-through requirements for each route instead of assuming that success on one proves compatibility on the other.

Use a feature-by-feature compatibility worksheet
Before buying a cable or replacing equipment, write the desired feature in one column and the requirement for each component in the next. This prevents a broad claim such as “supports Atmos” from hiding a missing link.
| Feature you want | TV check | Soundbar check | Source/content check |
|---|---|---|---|
| TV audio through one HDMI cable | Identify the ARC or eARC HDMI socket | Identify the TV-facing ARC/eARC output | Not applicable for ordinary TV audio, but app output settings still matter |
| eARC formats | eARC port, firmware and pass-through options | eARC output and decoder support | Player, app, game or disc must supply the format |
| Dolby Atmos | Check whether the relevant source route passes Atmos | Check Atmos decoding and the accepted input format | Atmos soundtrack and correct output mode required |
| One-remote volume and power | HDMI-control support and enabled setting | Compatible HDMI-control support and enabled setting | Optical cannot provide the HDMI-dependent behavior |
| Console or disc player at the soundbar | Accepts the video passed from the soundbar | HDMI input accepts the source’s audio and video | Source output and cable meet the required specification |
Mark each cell as confirmed, not listed or unclear. If a manual does not state a capability, do not treat the blank as confirmation. Look for the exact model’s connection diagram or ask the manufacturer with the full model number.
Questions to ask before purchasing a soundbar
If you are shopping for a bar rather than connecting one you already own, start with the TV’s limitations. A soundbar with eARC may still be a sensible choice for future equipment, but it cannot turn an ARC-only TV into an eARC source. Conversely, an ARC-compatible bar can be sufficient when your television, apps and sources do not require higher-bandwidth formats.

- Does the bar have a clearly labeled HDMI output for the TV, or only an HDMI input?
- Is that output ARC, eARC or both?
- Does the bar include an optical input if your TV lacks usable ARC?
- Does it have enough HDMI inputs for the player or console you intend to connect directly?
- Does its pass-through specification match the video signal your TV accepts?
- Does the package include the cable recommended by the manufacturer, or will you need to buy one separately?
- Are the audio formats you care about listed for the exact input you will use?
Do not pay for a feature solely because it appears in a family name or retailer headline. Confirm it in the soundbar’s own manual and compare it with the TV model’s manual.
Why included cables and accessories matter
Check the box contents before ordering accessories. A suitable cable may already be included, while a replacement may need to meet a stated class. Sony recommends a High Speed HDMI cable with Ethernet for eARC data transfer, but its guidance can vary for external-device and high-quality-format arrangements. Follow the instructions for the specific combination rather than assuming that an expensive cable adds a missing audio feature.
The cable is only one part of the link. Replacing it cannot add an ARC-labeled port to a television or eARC decoding to an ARC-only soundbar. If a new cable changes the result, it has corrected a connection or bandwidth problem; it has not upgraded the hardware’s specification.
A practical decision checklist
- Copy the complete TV and soundbar model numbers.
- Photograph or write down the labels beside every relevant port.
- Confirm the TV’s designated ARC/eARC port in its manual.
- Confirm the soundbar’s TV-facing ARC/eARC output and any HDMI inputs.
- Match the desired audio format against the TV, soundbar, source and content specifications.
- Choose a cable that meets the manufacturers’ stated class; check whether a suitable cable is already included.
- Enable the required audio-output, pass-through, ARC/eARC and HDMI-control settings.
- Use optical only when its format and control limitations fit your plan.
If any one of these checks fails, describe the setup as limited by that component. An eARC-capable TV cannot upgrade an ARC-only soundbar, and a premium soundbar cannot recover a format that the TV, source or content does not provide.
Frequently Asked Questions
How do I know if my HDMI port supports ARC?
Look beside the TV’s physical HDMI sockets for an ARC or eARC label, then confirm the same port assignment in the exact model manual. Do not assume HDMI 1, HDMI 2 or every socket supports audio return; manufacturers can provide ARC/eARC on only one port.

Can an ARC soundbar work with an eARC TV?
Yes, when the TV provides ARC on the compatible connection, but the link is limited to ARC capabilities. The eARC TV cannot give an ARC-only soundbar eARC bandwidth or formats.
Will my TV pass Dolby Atmos to a soundbar?
Only if the complete route supports it: the TV port and pass-through path, soundbar decoder, source device, output settings and actual soundtrack. An eARC label alone does not prove that every built-in app, game or disc will deliver Atmos.
Is optical audio as good as ARC or eARC?
Optical can be a useful digital-audio fallback, but its exact format support is model-specific and it does not provide HDMI-dependent power interlock or TV-remote volume control. Check both manuals before choosing it.

If the soundbar has an HDMI input and its manual confirms the required audio and video pass-through, you can route the player through the bar. This may provide higher-quality audio when the TV lacks eARC, but some system sounds may follow a different path and the bar must pass the video signal to the TV.
Do I need a special HDMI cable for eARC?
Use the cable class specified by the manufacturers. Sony recommends a High Speed HDMI cable with Ethernet for eARC data transfer, while some external-device and high-quality-format setups call for a higher-bandwidth class. A cable cannot create ARC or eARC support that the devices do not have.
Why does the soundbar work but show the wrong audio format?
Check whether the source is a built-in TV app or an external player, then verify the TV’s pass-through or digital-output setting, the source output mode and the soundtrack. The TV, soundbar, source and content all need to support the format.
The Bottom Line
Check the exact ARC/eARC labels and manuals for both devices, then match the desired format and control features across the entire signal path. eARC requires eARC at both ends; ARC-only equipment stays within ARC limits. Optical is a fallback with fewer control features, and an HDMI-equipped soundbar can sometimes handle a high-quality external source directly.
