Hey, just got everthing going, loving it so far!
Airplay is working no drama from itunes, and through the system, but I get the error below when I try to transmit using airfoil.
(Similar to this error https://github.com/abrasive/shairport/issues/213)

Is there something I can change to sort this, or is Airfoil not compatible?

Thanks!
Dean.

Hi guys,

I was experiencing the same problem but found out you don't need Airfoil on osx to stream to your RaspyFi. You can select the RaspyFi as output device in your System Preferences > Sound > Output settings.

Tip: you can also access this setting by holding the alt key and clicking on your volume icon in your taskbar.
