Sonos Arc & Amp surround setup

The Connect:Amp was required to be wired.  The Amp has no such requirement.

But the Arc does? (This is all current hardware)

No. And the C:A only had to be wired to the HT master player because the C:A lacked a 5GHz wireless card.

If the controller gets grumpy about bonding a satellite and talks about wiring, it could be that the system’s in station mode (i.e. on the WiFi) and the satellite is having trouble getting an IP via the HT master.

So further investigation. The following occurs on Android +/ iOS and on multiple networks.

Setup 1 (Sonos Net)

• Sonos Boost (hardwired)
• Sonos One
• Sonos Five
• Sonos Beam
• Sonos Arc
• Sonos Sub
• Sonos Amp

1. Arc setup with Sub and Amp (as surrounds) ✔️

Setup 2 (Sonos Net)

• Sonos One
• Sonos Five
• Sonos Beam
• Sonos Arc
• Sonos Sub
• Sonos Amp (hardwired)

1. Arc setup with Sub but can’t be setup with Amp (as surrounds) ❌

Setup 3 (Sonos Net)

A test to see if it is just a Boost allowing wireless pairing of Arc and Amp (as surrounds)

• Sonos One (hardwired)
• Sonos Five
• Sonos Beam
• Sonos Arc
• Sonos Sub
• Sonos Amp

1. Arc setup with Sub and Amp (as surrounds) ✔️
2. Doesn’t need to be a Boost hardwired

Results

So it seems you need a hardwired product to allow wireless bonding of an Arc and Amp (as surrounds) but the hardwired product can’t be the Sonos Amp 

@lewisc,
Isn’t it perhaps the case as @ratty mentions, where it appears your router is unable to assign an IP address via the main Sonos HT player to any of its bonded surrounds? It’s probably an incompatibility issue and you simply need to run your system in SonosNet mode to get around the issue, but do not wire a device acting as a Surround/Sub, instead use the Boost, or a standalone speaker instead.

Just out of interest what router is it?

As @Ken_Griffiths says, this is not a valid setup. A home theatre satellite -- and that includes an Amp driving surrounds -- cannot be the sole wired connection.

I don’t see a test with none of the units wired, i.e. in “wireless”/WiFi/station mode. The Amp should have bonded with the Arc fine (unless there’s a router issue with proxied DHCP requests).

Is there a reason that surrounds can’t be the hub? From our tests, that is the conclusion the I got… but why

It seems the dedicated 5Ghz connection from the soundbar to the surrounds is not really suited for constant two way communication.

As @106rallye says, the satellite connection is not suited for being the main trunk into the system.

• The bursty traffic demanded by other players in the system could affect the latency on the satellite's home theatre connection, and it has a very shallow buffer.
• The satellite connections fluctuate -- changing bands and channels -- when the HT setup is idle.

Great thanks, this was the thinking but couldn’t find it anywhere in writing
