No sound from Sub connected to Arc

I set up a new Sonos system today and am having problems with getting sound from the Sub. My system consists of the following:

--Two Sonos Ones connected by wifi

--Arc connected by wifi

--Sub paired with the Arc and connected to the router via ethernet

From the beginning, I cannot get sound to play out of the sub. I have tried all the usual remedies including resetting the router, powering off all Sonos devices, factory resetting the sub and reinstalling, and switching the Sub connection from wireless to wried. I checked by sliding the sub bass level back and forth on bass heavy content. None of these steps have helped.

This is the second Sonos system I have set up in the last 6 months and I had the same problem with my first system. When I installed a Boost via ethernet to my router, on my other system, that solved the problem. I do not have a Boost on my current system, but could acquire one if that is the solution (although it seems odd to have to have a Boost for the Sub to work).

Is it possible I got a dead Sub from Best Buy (I assume there are components that could fail that would render the Sub silent but sill allow it to connect)? Should I just take this back to Best Buy and get a new one and try again.

Any suggestions would be helpful. I generated a diagnostic code right before posting in the event that might be helpful (this is my first posting but it seems Sonos employees sometimes respond). It is frustrating to have this issue arise with both system I have purchased.

The diagnostic code is 641525654

I purchased a Boost, factory reset everything, and reinstalled after setting up the Boost first. The Sub works now. Odd that I need a Boost to get the Sub to work properly. This is the only thing that fixed my other system.

That sounds like a router brand (make/model) that does not support the main player (Arc) proxying the bonded device IP address - The master player (Arc) mostly uses an ad-hoc 5Ghz WiFi connection to talk to the sub, when it’s bonded, and its IP address is ‘proxied’ via the Arc from the routers DHCP server. However… One or two routers don’t like to supply IP addresses via a proxy. I suspect that might have been your issue. Placing all on SonosNet usually resolves the issue, as it did on this occasion. Just curious though, what make/model of router are you using?

I think the best you can do is connect only the Arc to ethernet. That will then -after reboot- create a network voor the one’s and sub. If you only connect the sub with ethernet, it doesn’t work.

Agree with @JeroenVR . Having only the Sub wired is a major mistake. Wire the Arc, leave Sub and surrounds wireless, Do NOT ‘Disable WiFi’ in the Arc settings (nor on any other device).

Power off all your Sonos devices, power on the Arc, then your other devices.

The arc is not in a location where it can be connected via ethernet. So, it sounds like I should not connect either one via ethernet. I tried that configuration and it didn’t work.

You are correct that much better to wire nothing than just to wire the Sub.

You will have to give more detail than "it didn't work". What did you do? How did it fail? Were there any warning messages?

Please also give details of your network. Simple router? Mesh? Access points?

As a temporary thing, if no joy with nothing wired, can you physically move a One and connect that to Ethernet? Don’t allocate it a new room or anything. Then try setting up the Arc and Sub.

I factory reset both the arc and sub and reset up with just WiFi connections. The sub still isn’t working. If a Sonos employee looks at this on Monday, the diagnostic code is:

Are you perhaps playing a PCM 2.0 audio source, rather than 5.1 surround sound? What is your Sonos App ‘now playing’ screen showing as the audio output from the TV?

Have you tried playing a music audio source from one of the various sources available in the Sonos App, like Sonos Radio, for example?

Hi Ken. Do we know why adding the Boost would fix an IP Addressing issue? I can't immediately think of how this would do it
