I see events on the input device that's associated with the jack, though I don't know how that gets routed inside ALSA. In any case, the module option seems to bring it back to a working state. Any hints as to what to do now for the PulseAudio bug report if I wanted to diagnose and report this is a UCM problem? Cheers
