On the page on the wiki about developing modules at: <http://pulseaudio.org/wiki/WritingModules> There's a nifty little tutorial on writing a plugin. Handy stuff. The pulsecore headers are all referenced with prefix "pulsecore", as in: #include <pulsecore/module.h> I fished around for any pulse related -dev pkgs that I had not installed, but nothing obvious showed up in Synaptic. So I copied the pulsecore directory from the pulse sources to /usr/ include and deletec the c files. I also needed to copy the config.h file from the pulse directory to /usr/include/pulsecore My test plugin builds and loads. Am I missing a package or is the method outlined above the way to go (it works on my machine(tm) :) Thanks Nick
