If you want to transmit Dolby Atmos from your TV to your AV receiver or soundbar, your TV must be equipped with at least HDMI ARC. As we mentioned above, HDMI ARC works with Dolby Atmos/Dolby Digital Plus, but if your TV is equipped with the newer HDMI eARC standard, it will also work with Dolby Atmos/Dolby TrueHD.
Does Dolby Atmos need HDMI eARC?
No, eARC is not required for Dolby Atmos to work. Dolby Atmos can work with regular HDMI ARC through the Dolby Digital Plus audio codec. However, those wanting Dolby Atmos TrueHD must use eARC. You can also bypass ARC entirely by connecting the media device directly to the soundbar or AV receiver.
How do I know if ARC is playing Atmos?
If Arc is receiving an Atmos signal, we will display that within the Sonos App on both the “Now Playing” screen, and within the settings portion of our app.
Can you pass Atmos through optical?
Digital optical doesn’t support Dolby Atmos because it can’t transmit the Dolby Digital Plus or Dolby TrueHD audio codecs (both of which can contain Dolby Atmos audio). Digital optical cables only support up to 5.1 channels of audio. HDMI is the only method to send/receive signals with Dolby Atmos.
Can you hear the difference between ARC and eARC?
If your TV is HDMI eARC enabled, but your AV amp or soundbar is only compatible with HDMI ARC, you’ll likely get a sound – but the bandwidth restrictions of ARC will mean you won’t be able to experience the high bitrate audio that eARC can provide. So no, it’s not backwards-compatible.
Is eARC better than ARC?
The main difference between HDMI ARC vs eARC comes down to bandwidth. Since HDMI 2.1 has a higher bandwidth than HDMI 1.4, it can transfer more data faster. That means the audio signal doesn’t have to be compressed as much, and you’ll get better audio quality with eARC.
Does HDMI support Dolby Atmos?
Dolby Atmos sound can be transmitted through any HDMI cable, including HDMI 2.0. However, you also need to be sure that all devices involved, such as the TV, are capable of delivering Atmos.
Is 5.1 the same as Dolby Atmos?

How do I get Dolby Atmos on my soundbar?
Connect the HDMI output (ARC) port from the soundbar to the HDMI (ARC) or HDMI (eARC) Audio-Return Channel enabled port on your TV. This allows Dolby Atmos audio to flow from the TV apps or other devices connected to the TV via HDMI. Although most new TVs are capable of this, older models may not be.
What’s better optical or HDMI ARC?
HDMI ARC or digital optical audio? HDMI ARC is a better option. It supports Dolby Digital Plus, Dolby Atmos, and up to 7.1 channels of uncompressed audio while Digital Optical only supports Dolby Digital and up to 5.1 channels of uncompressed audio.
Is it better to connect Soundbar with HDMI or optical?
Both cables can be had pretty cheap. The biggest difference is that HDMI can pass higher-resolution audio, including the formats found on streaming services such as Dolby Atmos and DTS HD Master Audio. These formats can’t be transmitted across optical. In terms of simplicity, HDMI also passes video signals.
Can HDMI 2.0 do Dolby Atmos?
HDMI 2.0 a/b connections and cables can manage up to 18Gbps bandwidth A/V signals. Despite this hardware great capability, the ARC function is limited to just 1 Mbps bandwidth.
Do you need eARC for Dolby?
NO- Not if the Dolby Atmos sources are passing through your TV. Keep in mind that both your TV and soundbar or home theater receiver have to have HDMI-eARC connections in order to access Dolby Atmos via the TV to your soundbar or home theater receiver.
What HDMI do I need for Atmos?
Dolby Atmos sound can be transmitted through any HDMI cable, including HDMI 2.0. However, you also need to be sure that all devices involved, such as the TV, are capable of delivering Atmos. For equipment that can handle HDMI eARC, HDMI 2.1 cables are recommended, but HDMI 2.0 cables will work fine.
Do all HDMI cables support Atmos?
For “Dolby Digital Plus” devices, any Premium High Speed (HDMI 2.0) cable or later should support Atmos over ARC (including all the cables on this list). However, if it’s the lossless “Dolby TrueHD” format, you’ll need the additional bandwidth of an HDMI 2.1 cable.
Do you need eARC?
Without an eARC port on your TV, it won’t matter if you have the most expensive Blu-ray player connected to one of its other inputs — you won’t be able to transmit hi-res, lossless audio (whether Dolby Atmos or any other format) to your external audio devices.
Do all HDMI cables support ARC?
There is no such thing as an HDMI ARC cable. Any HDMI cable will work universally for HDMI and HDMI ARC/eARC ports. Only a few very outdated HDMI cables could potentially struggle with some of the higher quality audio formats with eARC, but this is unlikely to happen.
Do I need a special HDMI cable for eARC?
Not all HDMI cables can let you experience the full capacity of eARC. Some HDMI cables do not have enough bandwidth to carry high-frame-rate video and high-bit-rate audio channels. However, high-speed HDMI cables with Ethernet are enough to support eARC, just like the next generation Ultra-High-Speed HDMI Cables.
Is HDMI 2.1 the same as eARC?
The eARC is a feature implemented in the latest HDMI 2.1 specification, the biggest advantage is that it exceedingly improves bandwidth and speed. This allows you to transmit high quality audio from your TV to your Soundbar or AV receiver and is compatible with the high bitrate formats Dolby Atmos and DTS.
