Setting up audio output without X11

[trestrantham]

Have you had any luck setting up audio output for this container without X11? I'm trying to host this on Docker Cloud and serve via Icecast.

No, but didn't try. Do you have PulseAudio without X11?

@wernight Why would we need PulseAudio. If MPD serves a HTTP stream or streams to icecast (or both at the same time) would be fine if u ask me.
Than u can use other MPD on a Raspberry Pi or simular play the music hosted on your server.

If you can document the usage, I'd be happy to accept your PR.

I've updated the README and merged the pulse audio native. Should help.
