So basically, I got it to work. The button on the switcher activates the macro and plays the audio file in rdairplay. However, there is no sound, due to rivendell competing with the soundcard installed on top of the gpio. Not sure there is any way to get around that except to use the pi onboard audio. This is a Pi B+. I'm guessing that it just is not workable.
