FWIW, I think it has gone after changing System > Sound to "ALSA" for sound events (was on Autodetect). I've only noticed this issue on Pidgin notifications and those are working normally now. Changing to ALSA in Pidgin Prefs didn't make any difference, however. Not a fix but a workaround, seems definitely in Pulseaudio.
