Esound

EsounD (the Enlightened sound daemon) consists of a set of tools to allow simultaneous use of an audio device by several applications.

Without its use, a program currently using the sound device must finish before another application can output to it.

Esound also offers accessing/playing audio over audio devices over a network.
