My Mac has two sets of speakers connected to its analog and digital outputs. I am currently using (with a great success) AirFoil Speakers to stream audio from iTunes/iOS to the analog ones (digital ones would work as well but only one at a time).
Is there a way to run two instances of AirFoil Speakers to make my mac appear as two different airplay devices, allowing me to choose to which speakers to output the sound?
I have tried force running another instance of AirFoil Speakers only one of them shows up in a list of available devices.
I guess I could install a Windows-based VM with sound support and run another instance there but that is a bit too much.
