I'm trying to send audio over airplay (RAOP) from Ubuntu 14.04. The pulseaudio-module-raop in Ubuntu used to support my 2nd-gen Airport Express, but it no longer appears in my list of pulseaudio sinks. It's been 6 months since I used it, with a lot changing on my system, including a successful upgrade from 12.04 to 14.04. Somewhere along the line I assume something got misconfigured or maybe a prefs file deleted.
I've enabled "Make discoverable Airplay AirTunes" sound devices locally. I've tried deleting the pulseaudio preference files I can find and uninstalling/reinstalling pulseaudio; airplay still doesn't work. I even upgraded to the in-development pulseaudio 5.0 - same results. Pulse seems to work fine except it doesn't "see" my Airplay devices.
As an experiment, I built the experimental RAOP2 version of pulse. It sees my devices and can send audio to them, but it has to be be manually launched and I'd rather be using something from a ppa for updates, etc. I know it used to work so I want to get it (not the experimental raop2 - I already have that working) going again.
Not sure where to look next.
