Is it at all possible to broadcast the usual audio output to an iPhone or similar device? So sort of audio server (Desktop) to client (iPhone).
more details: Ubuntu 10.04/11.04 or 11.10, iPhone 3S or 4. It is my understanding that the sound system shipped in Ubuntu can be used as a sound server. The idea would be for the sound system to stream to a remote audio client, for example sitting in a different computer or an iPhone, that computer/iPhone could be connected to a audio amplifier in a different location than the computer where sound/music is played from. The streaming is of course by means of a local (wireless) network. (Although via bluetooth can be a solution also)
By running an Icecast server we are able to stream our local sound to any device that is capable of tuning in to an Icecast/Shoutcast internet radio stream. I don't know if an iPhone already comes with this functionality but there likely may be an app to make this possible.
If you prefer a graphical frontend rather than a command line solution to start the streaming service you may try out stream2ip.
