What is XBian? Well at least you could start from here http://www.xbian.org/what-is-xbian/
XBian has custom Debian build under the hood, not like other distros which serve only as media players. XBian is a full OS
Sound? Alsa vs something? nowhere near as for default HDMI or build in Analog audio out alsa is not used. That is only for external sound card connected through USB for example
BT audio and other wireless stuff is not very common, to be honest guys like you who would like to use this with RPi can be counted on one hand

Logitec G930's dongle is an external audio card

By no mean I'm an expert on unix let alone Kodi, but since OpenElec, OSMC and Xbian are all based on Kodi, I think it's safe to assume they all have similar(if not same) systems running on background.

I'm aware OpenElec is stripped to barebones. But it still runs for example the same CEC plugin Xbian uses. Also they all use OMXPlayer.

Basically my question is, what's the difference between Xbian's audio system and other Kodi based OSes.
