Ossplex is a simple sound server that emulates a new Open Sound System sound device. This allows any number of applications to share the sound device without the need of the hardware mixing support. It uses fusd library/kernel module to create a character device driver in user space, hence it is fully transparent to all oss using applications.
You can download ossplex from sourceforge. For more information, see this README.
