Hi Lennart, Thanks!!! I've applied the patch on 0.9.13 and pulseaudio successfully opens the device during initialisation stage!!! :) However the "Operation not permitted" error still comes when I try to play something via pulseaudio (just a test in gnome-sound-properties) and the pulseaudio process aborts eventually.  Output is attached.  See if you have any clues?
