If you do, the settings in XBMC have to change accordingly (HDMI = hdmi, S/PDIF = iec958) Apparently PulseAudio and ALSA drivers conflict - which will lead to NO sound in XBMC; Start by removing PulseAudio sudo apt-get remove pulseaudio gstreamer0.10-pulseaudio; Now purge all remaining PulseAudio files from the system
