Yahoo! I've got pulseaudio xbmc passthrough working. I've rolled it together with a "previously" windows c++ library called Ac3Filter. I've been tweeking up Ac3Filter quite a bit. I'm using the Ac3Filter library to Mux spdif. It was a well written library/tools that was relatively easy to get ported to linux. I'm watching Avatar in wonderful DTS surround sound now.
