Yes, default.pa I'm using is the one shipped with 0.9.21 indeed. You told about the problem being with module-udev-detect, but the fact is that at anytime I had disabled him, and using module-alsa-sink and module-always-sink always triggers the problem, that's why I related the problem to those modules. I don't know if this will be of any help, but I'm developing my distro inside VirtualBox, I remember of sawing a post of Colin Guthrie which Lennart answered too about some problem with PA and VM (http://www.mail-archive.com/pulseaudio-discuss at mail.0pointer.de/msg01293.html), well I had discarded the idea of the problem being with the VirtualBox since I copied my system direct to a real box and the problem persisted there too, but at this point I really don't know if it is related or not. Do you think this problem is related with this specific version of PA? Maybe I could try using an other version, like 0.9.19 same I have on my Ubuntu. [ ]'s --- Maginot Jr
