Public bug reported:
This bug manifested itself only recently (kernel update?). I have sound
through the internal speakers but nothing (except occasional clicks)
through the headphones. 'What device did you plug in?' dialog appearing
fine, headphones show up in sound preferences, test sounds not audible.
