PulseAudio can be run in one of two modes these are: Passthrough Mode Used if you want to passthrough (bitstream) AC3, DTS, and EAC3 to an AVR or other device. In order to allow passthrough to work with PulseAudio then it MUST be set to use a 2.0 channel configuration, despite the 2.0 setting this will still allow 5.1 audio from AC3, DTS, and EAC3.

12.04 - XBMC Passthrough Audio and Pulse - Ask Ubuntu
https://askubuntu.com/questions/145052/xbmc-passthrough-audio-and-pulse
Both Stereo audio and passthrough work within XBMC without having to uninstall pulse.

XBMC, Ubuntu 10.10 and PulseAudio | XBMCworkshop

The passthrough audio device setting worked fine (used for media with surround sound such as DTS 5.1), but the audio output device did not. Sound through Pulseaudio sometimes gave a metallic, distorted sound and sometimes just complete silence, regardless of the application used.

AC3 (Dolby Digital) is signed 16-bit little-endian 2-channel 48kHz PCM data (as far as we want pulseaudio and ALSA to be concerned), but the default pulseaudio sample-rate is 44.1kHz, so when an application attempts to connect to pulseaudio for passthrough pulse rejects the connection because of the sample-rate.

Ubuntu 14.04 + XBMC 13 (or KODI) + Intel NUC i3
https://blog.serindu.com/2014/05/12/ubuntu-14-04-xbmc-13-intel-nuc-i3/
XBMC 13 does finally let XBMC play acceptably with Pulseaudio by default which is nice for a lot of people; but it does not support passthrough for either DTS HD-MA or Dolby TrueHD. And since one reason I was upgrading from a Raspberry Pi to the Intel NUC was to get my full HD 7.1 channel audio working correctly I didn't like that option.
