Right now I'm coding on the sound system to ZeroFps. We will use OpenAl and Ogg and now the focus is on improving the OpenAl support with better 3d sounds, distances and all other strange parameters that sound people can not live without. To start with we will only support the parameters min range, max range and looping and then we will add more things as we need them. In the future I hope to add some real cool sound system like thief where the sound really traverse the corridors :).
