Headless playback/timeout?

Hi all,

 

I've got a few Pi's/Plex's dotted around the house, and one of them isn't plugged into a display.

 

Does that stop Plex booting properly? I can certainly see that it has been assigned an IP address by my router (wifi), but I am unable to play music to it.

 

I would really like to Pi's behind a few sets of speakers and just play music to them with my remote, but the remote can never 'see' the Pi/Plex when there isnt a display plugged into it. I've tried it with a couple of Pi's that I know work with displays, to eliminate the possibility of it being a faulty unit.

It does not really solve the issue with Rasplex but have you considered the other PI AirPlay sever options (I assume this is all you really need)?
