That is for Ubuntu 14.04, not 12.04... but I was able to built last git 
master branch (small problem with switching to gcc-4.8 for C++11 
support) and install it...

So... I tested pulseaudio from last commit in master branch on Ubuntu 
12.04 with KDE4 desktop. Without module-card-restore it is working 
perfectly, no problem.

With active module-card-restore there there is one big problem, both 
modules module-bluetooth-policy and module-card-restore start to fight 
with changing profile between a2dp and hsp. module-bluetooth-policy 
wants hsp, but module-card-restore wants revert back to a2dp. Anyway, 
fix for this is simple. I tested it and expect git format patch on 
mailing list in few minutes...
