[linux-audio-dev] alsa ethernet streaming?

Hello, I would like push audio streams over ethernet and was wondering what avenues people have tried. I intend to have two linux boxes (or more). Box1 has the user interface and all of the audio data. Box2 has no user interface and is plugged into an amplifier and speakers. Eventually I would like to have many Box2's. I envision an application with a server running on box2 and a client running on box1. Ideally the client would create an ALSA input and the server would create an ALSA output. Then, the client connects to the server, any ALSA enabled app connects to the input created by the client, and audio is heard from the speakers connected to the server. I have no expectations that such an application actually exists. I'm curious as to what options do exists to push audio over etherenet. -Garett
