Hi, You should take a look at the bug report system to see if it something known.

Yeah. It happens when you copy&paste without double check comments and you're afraid about "it could not work" :) Thanks!

I confirm that adding the pthread library did the trick. But the question "why" is still there :)

They do but I guess that since CoreAudio comes before PulseAudio alphabetically, it's the one getting selected.
