Again Oxygen sounds were broken but this time I can't find the place in settings where I could set those sounds. As I recall, they were in Notifications but now it all looks different so I have no clue where to look. Any idea?
EDIT: I found it... sort of. There is the setting for Power management but I can't find anything for system events like session startup or changing the volume level from the keyboard.
The problem is, oxygen ogg files are there but nothing plays, every sound is mute (there is sound in movies or music), even sounds from other (non oxygen) files, so the whole Notification sounds are broken.
