add 2 new folders to folderview:
mark 1 folder and hit "Del" to move to trash-> confirmation dialog popup comes up with sound
Del next one-> same dialog somes up, but no sound is heard

Looks like KNotification bug. I'll take a look.

Fixed with http://commits.kde.org/knotifications/55d6c866054ff09f1ab55ae68e85a9c39e6148cc

awesome thanks! will try in next kci :)

star-buck commented 9 years ago

seems still delayed or shaky, not sure how to reproduce though... will keep this open for a little longer...

system sounds like "delete - confirmation popup notify sound" have a delay of about 2-3 seconds on several machines under plasma5 (under kde4 the notifiy sounds were almost immediately on same machines).

mck182 commented 9 years ago

2-3 seconds sounds quite high o_O

So here's exactly what happens when the sound should be played for the first time in any application:

New KNotification object is created (in case of dialogs it's KNotification::event(..))
The config file with the sound file path is loaded
Phonon is initialized
Phonon is passed the file path from the config
Phonon plays sound

The only place where it could be slowed down is either the config file loading or Phonon initializing things or the sound file being loaded from disk. I don't think the config file loading can be speed up any further, so we'd have to look at Phonon.

Which Phonon backend is used on those systems?

star-buck commented 9 years ago

yeah, somtimes its <1sec, sometimes between 1-2 seconds and also sometimes longer... since using kde4 gets you trained like a pavlov dog to expect a sound here and there, you keep waiting for it under plasma5, and in case of > 2-3 seconds almost give up on it and go on and then the sound still gets played. :) Phonon in Netrunner uses gstreamer backend default, I yet have to thouroughly test if this happens mainly under dolphin4 or also when adding files to folderview containment, then mark them and delete.
