Overview

This goal of this setup is to put the Sonos speakers on an untrusted network to keep all but the required traffic away from the trusted network where devices like personal computers, phones, etc. live. This write-up assumes you already have two networks setup and working.

Important Note on Unifi OS 3.x

UI broke cross-VLAN multicast DNS in this version. See below for steps to install the multicast-relay script to re-enable this. Without it, your Sonos controller app will not be able to discover your speakers on the other VLAN.

System

I have a Sonos Playbar, Sub, and 2 Play:3's as rear surrounds as one home theater setup connected to a UDM (non-Pro, but this should work on Pro too). Some of this setup may be easier for people with non-paired speakers, as Sonos does some shenanigans with which speaker is actively sending traffic to your wifi.

Reproducible Builds for macOS

There's a neat writeup I stumbled across recently titled "Reproducible codesigning on Apple Silicon" from Keith Smiley about some gotchas when it comes to compiling a binary in a way that's repeatable and always generates the exact same byte output (which would then checksum to the exact same hash) - even if compiled on a different Mac.

In applying the suggestions I found in the blog post, I found a few other corner cases that I just wanted to get documented more explicitly somewhere.

Tools Matter

Footnote 2 from that blog post is important:
