If I change the volume of the notification sounds (systemsettings5 -> Multimedia -> Audio Volume -> Applications -> Notification Sounds), notifications still keep appearing with maximum volume sounds all the time, which is very annoying if you use all other applications at a lower volume.
It only works with gstreamer and vlc (with libvlc 3.0) phonon backends.
David, what backend are you using? VLC prior to version 3?
I'm using Phonon VLC backend. I have libvlc 3.0.1 installed (libvlc-bin, libvlc-dev, libvlc5, libvlccore9), although in the settings (Multimedia -> Audio and Video -> Backend) it says Phonon VLC 0.9.1.
Thanks! ...Other david, any ideas?
Try with phonon-gstreamer
Funny, now with Phonon Gstreamer I get no notification sounds at all, regardless of what I put in the settings.
