I'm trying to stream audio from my Ubuntu laptop to an Airplay device, and I'm having significant issues. I've installed "paprefs", made discoverable Apple AirTunes sound devices available locally, and I can see the speakers I want to play audio to as an option in my sound setting, but when I select it, no sound is played at all, from either the speakers or my laptop. Help would be much appreciated. If you need more information about my setup of setting or whatever, I'll put that up ASAP.
