Description Kai Uwe Broulik 2011-06-02 14:56:23 UTC
Version:           2.4.1 (using KDE 4.6.3) 
OS:                Linux

I have set my Fade out on Stop to 500ms. When I press Stop, it takes a second for the fade to start.
It should instantly start fading when I press stop, not after a second or longer.
This makes me disable this feature everytime since I cannot stand this behavior.

Reproducible: Always

Which Phonon backend do you use?
Comment 2 Kai Uwe Broulik 2011-06-02 22:25:23 UTC
The great working *cough* Gstreamer. But it has been that way since I started using Amarok, so it’s no problem of Gstreamer. I use Amarok since 2.0 / KDE 4.2
Comment 3 Torrie Fischer 2011-06-03 12:02:03 UTC
And what version of the amazing GStreamer backend might you be using?
Comment 4 Kai Uwe Broulik 2011-06-03 14:30:02 UTC
libgstreamer0.10-0 (0.10.32-3-ubuntu3)
But as I said, this behavior has been there since ever and not just with Gstreamer, it is the same when using Xine.

Sorry if I wasn't clear, but I mean the Phonon GStreamer backend. Phonon-GStreamer can use any version of libgstreamer.

phonon-backend-gstreamer 4:4.7.0really4.5.0-0ubuntu2.1

The VolumeFaderEffect class was tweaked in 4.5.90.

Additionally, I've noticed that Pulseaudio sometimes buffers a *lot* of data, causing the fade out to take a second or so before it hits the soundcard. Thats something I'm working on soon but if you can test the 4.5.90 release and see if anything is any better, that'd be much appreciated.
Comment 9 Kai Uwe Broulik 2011-09-20 11:05:19 UTC
But what has Phonon’s buffer to do with fade? When I adjust the volume, it instantly gets changed ;) Can’t the fade out effect be handled via volume control or something?

Is this still valid with Phonon-backend-gstreamer 4.6?
Comment 11 Myriam Schweingruber 2012-07-30 20:21:43 UTC
Closing for lack of feedback. Please feel free to reopen this report if you can reproduce this with the gstreamer backend version 4.6.1 or later.
