After several days of trying and failing miserably in every attempt of removing RaopX’s need of a temporary audio file to stream from I got fed up and had to work at something else for a while. I got my mind tuned in on Zero Conf or Bonjour as Apple calls it. I used a few nights to write a small Zero Conf module and had it implemented into the project this afternoon. So, as of version 0.0.4 RaopX now supports Zero Conf and because of that no longer needs any input parameters at startup. The Zero Conf module will search for any airtunes capable devices on the network and if it finds more than one present them as a menu. If only one devices is found it will just connect without any questions. The location of the temporary file is now hardcoded, and if RaopX is terminated in an ordinary fashion the file also gets deleted. If for some reason the file exists at startup it will be removed before recreated to save storage.

Here is a screenshot showing RaopX 0.0.4:

A friend and I have just started to work an open source AirportExpress client for Os X. The client is based on raop_play version 0.5.1, and has the working title RaopX. The original raop_play let’s you stream audio files from your computer to your AirportExpress base station. RaopX will instead let you stream audio from any application you’ve got on your Mac to the AirportExpress. The initial version will stream any audio that comes in on the default input device of your mac, and will depend on the routing functionality of e.g. Soundflower to achieve the desired functionality. The goal is to have no dependencies to other applications in the end, but we’ll have to see how things progress as we move along.
The project is currently in it’s very early stages, but the status as of today is that we’ve modified raop_play so that it compiles and run’s on Os X and incorporated an input audio queue so when routed through Soundflower we’ve got audio through to the AirtportExpress.
The hard part still remains though. RaopX still plays files, so everything coming in is stored to a temporary file before being sent to the AirportExpress. In other words: we still have a very long way to go.
Updates will be posted here reporting our progress so check back soon.

This guide is for Ubuntu 9.04 Jaunty Jackalope and will show you how to stream audio from any application to your AirportExpress. PulseAudio has built in support for AirTunes/AirportExpress with version 0.9.15. Unfortunately it did not make the Jaunty release, but installing it yourself is a small task. This guide will show you how. (Guide is updated for 9.10 Karmic Koala)
