AudioBridge runs in the background on your computer and creates an AirPlay device for each Sonos speaker group on the same network. Choose which speakers to AirPlay-enable, give them a custom name, and start listening to any audio you want. Apple Music, YouTube, SoundCloud, podcasts, music blogs, you name it.

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.
Pros:It provides a simple method for Airplay to Sonos
Cons:A Windows version or better still something that can run on a router or the Sonos Bridge.

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!
Pros:I can finally send music to my Sonos speaker via AirPlay!
Cons:I wish this were built into Airfoil!
