How to stream music to a PC? How do I use my Mac to stream audio (preferably using AirPlay) over WiFi to my 2 PCs with sound systems?  (If at the same time, then they need to be in perfect sync)

It would also be nice to be able to clone the display, but that is a very far second in priority.

These machines are on a network with no internet access, but the Mac is on a second network with internet access (do not want to bridge the networks - out of the question).  I'd like to be able to control the audio playing through the PC with the Mac.  I know AirPlay supports stuff like this, but I need to figure out how to get an AirPlay receiver running on my PC.  Even a VM of a standalone receiver would work...

Mac version OS X 10.11 El Capitan
Windows version Windows 7 Home Premium
Windows version Windows XP Professional
Install iTunes on both computers
Sign in to Home Sharing on both using the same AppleID (it doesn't have to be the same AppleID as you use for store purchases)
Leave iTunes running on both.
Follow the help on the PC to select the Mac's music library and stream away.


Since you have added a lot of extra requirements to your question, I would just set up a Home Stereo system and have the playing computer use bluetooth or a cable connection to input sound to the amplifier/receiver. I use a belkin unit, but there are many at inexpensive prices and then you can use an iOS device to remote control the selected iTunes instance.
