Why is xbmc trying to use PulseAudio?

I installed xbmc Eden release on a fresh ubuntu 12.04 x64 full desktop installation. I realize this is beta software, but I am having other problems with ubuntu 11.10 and this is a test for that.

I forgot to remove PulseAudio before I installed xbmc. I have no audio with music or video. I have since removed Pulse audio and xbmc was still trying to use it. When I attempt to play a video or mp3, the log file has several of these error messages:
XBMC is obviously still attempting to use pulse. I decided to remove xbmc with:
apt-get reported that all the xbmc configuration files were removed.

I then re-installed xbmc. The nfs shares, and all other configuration settings were still there. When I tried to play audio, I still get the same pulse audio errors.

Surely there must be some persistent configuration file that tells xbmc to use pulse. Where is this kept, and what should I change it to?

Just the try pulse if not avail punt to alsa code that triggers those msgs..

Get your alsa working and you will be fine.
