Hi @isthatmysandwich

Welcome to the Sonos Community!

In direct answer to your question, Sonos supplies HDMI 2.0 cables.

The following response from @Rhonny is correct:

@isthatmysandwich

1.4 is generally fine for streaming services’ Atmos.

2.0 is needed for TrueHD Atmos via Blu-ray for example.

We used to supply HDMI 1.4 cables with the Beam, for example, but with Beam 2, Arc and Arc Ultra, we now supply HDMI 2.0 cables for use with eARC.

I hope this helps.

Technically, HDMI 2.0 refers to the HDMI port specification, not the cable type.

Hi @Mr. T

That’s not entirely accurate - 2.0 cables have a wire present that 1.4 cables do not have. It’s not always a question of shielding and bandwidth.

You’re missing the point. Read the Sonos reply in the link I posted earlier.

Hi @Mr. T

I have - the post clearly states that only HDMI cables with HEAC support eARC. Not all HDMI cables support HEAC, therefore cables do have specifications.

I never said cables don’t have specifications, but as per that post it also clearly states “Cables aren't rated by HDMI version”.

Yeah, I don’t know where they got that little titbit from - it’s not mentioned in our documentation, and they did not leave notes for reference.

It does not appear that they got it from Wikipedia: https://en.wikipedia.org/wiki/HDMI#:~:text=HDMI%20Ethernet%20and,%5B54%5D, so I’m not sure where it came from.

I hope this helps.

They may have if they read the Wiki section on Cables and HDMI Cable Certifications.

I think what your colleague was intending by their statement was referring to the supplied cable by its official name as per https://www.hdmi.org/resource/cables

A simple Google search also provides the following reading Why shouldn't HDMI cables be labeled with version numbers?
