There is code with prolog predicates (or terms? :-)) and some ini file. You can look at package policy-settings-rx51: https://gitorious.org/community-ssu/...-settings-rx51
I will prepare more (maybe all) cssu versions of pulseaudio (DEB packages). Is there some tester who want to teste all versions and write which version working and which not? I have no other idea what to do with non working sound, because I cannot reproduce it on my n900.
