This is an ancient post, published more than 4 years ago.
As such, it might not anymore reflect the views of the author or the state of the world. It is provided as historical record.

For some time now I have been trying to craft a WiFi Soundcard from my Neo FreeRunner (running Debian). Still a long way to go, but after few hours of heavy fighting I finally have some success. Namely, I was able to (kind of) play a song on my lappy through PulseAudio, via UDP/RTP, to PulseAudio on the Neo and hear something (very distorted, but discernible).

So, state of the art for today is:

  • basically it should work out-of-the-box;
  • the WiFi link here seems too weak/unstable for a full 44100Hz stereo;
  • for the time being it works only after joining the multicast group manually with mcfirst;
  • sound quality is awful (due to the above problems).

But I got some sound through. Will be working on it some more in my spare time.
