AudioBridge adds AirPlay support to your Sonos speakers with an easy-to-use Mac menu bar app.
Extremely simple to set up and appears to "just work". Hopefully Apple won't break it with changes to the AirPlay protocol down the road!

I wish this were built into Airfoil!
While I bought the product immediately, it is more to support the author to improve the product. I listen to my Sonos a lot but I don't necessarily keep my MacBook Pro on all the time. That dependency needs to go. I do hope this continues to work. Apple is quick to change protocols and kill interesting products like this.
It provides a simple method for Airplay to Sonos
A Windows version or better still something that can run on a router or the Sonos Bridge.
