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.

Shoutcast Metadata Protocol
How To Parse Titles from MP3 Streams
I wanted to add the ability to show titles from Shoutcast streams on the SliMP3, like Winamp does. The protocol isn't documented anywhere officially (of course). So I ended up cobbling together info from google caches, xmms source code, and mailing lists. Hopefully, this document will save others from the same fate.
