Trying to connect the Sonos Arc to Samsung Frame wirelessly

Hi.  You cannot do this I am afraid.  Your TV is incapable of sending anything to a Sonos Arc wirelessly.  Or to any other soundbar, for that matter.  If you believe you were told it would then you either misunderstood or were misinformed.

It can’t be done, all Sonos soundbars require a wired connection to the TV set. Depending on the device on either side, that’s either optical, ARc, or eARC. There is no device that Sonos makes that will wirelessly connect to a TV set of any make. 

Are there no workarounds like using Apple TV or something?

The obvious workaround is an HDMI cable. 

The I guess this was a bad decision… my Marshall’s connects to my fire stick in the projector and tv using Bluetooth… sad I liked the sound quality on this one.

So a technology designed to carry stereo music works with speakers designed to play stereo music.  You have bought a television.  The Arc is designed to play multichannel audio in an AV context, including Dolby Atmos, via a wired HDMI connection.

The salesperson here sold the Arc to me on the pitch that this can be a “wireless” soundbar doubling up as a hub when paired with the sonos one and the bass module. My sole criteria for the purchase was “wireless”… having experienced the same with the Marshall via bluetooth before… Now since that is not possible with the arc I’m disappointed.

I can understand your being disappointed if the salesperson created expectations that could not be met. 

I am not sure what the salesperson could have meant by a "hub" in this context either. What were you hoping for?

Like all Sonos speakers,  the Arc can play music sources wirelessly. 

Yes that is what i was hoping for… I was planning to add the bass module and a couple of sonos one’s to the mix (in the same room) in order to create a home theatre like experience without having to connect them all through wires. I’m actually ok with the TV being connected to the ARC with a wire (though i might have to buy one that is longer than the one provided and any suggestions for that are welcome) but i cannot see how this will work with my projector which has just one HDMI port where i usually plug in the firestick...

Disappointed with the sales person I presume?
