Version: (using KDE KDE 3.5.5) Installed from: Mandriva RPMs As I have had the chance of trying out microsofts newest operating system, I noticed one particulary nifty (and useful) feature in the mixer panel. It is now possible to change volume level on an application-specific level (directly in the volume mixer panel), and even mute sound from specific applications. This is something I, and others, would like to see as a feature in linux and KDE.
Created attachment 18701 [details] Screenshot of the volume mixer in vista Please review the attached screenshot
I currently lack the time to implement the GUI for this. The necessary groundwork is already done.
I've heard that Photon was supposed to support per-application audio settings. It would be nice to have this in the GUI, please keep working on it.
For anybody with some spare time: take a look at phonon/examples/outputselector.cpp. It does implement the basics to do volume control and device selection for all Phonon applications.
I tried and compiled phonon/examples/outputselector.cpp. It works, even if it would need a better gui, but it can control only the apps that use Phonon. It would be really useful to have something library agnostic, like PulseAudio.
It is possible if you install pulseaudio. But this breaks a lot of other features (especially on Kubuntu), so in my case my headset did not work anymore, but you could change the volume of every stream. Just wait a bit and it hopefully gets implemented.
Closing this as FIXED on the Phonon level. It is nowadays possible with PulseAudio (and supposedly it simply works(tm) on Windows too) and even nicely integrated in KMix. We do not think there would be much use in replicating functionality that is already there, at a lower level, thus covering also applications outside the Phonon scope which is of course to be preferred over a Phonon-only solution.
*** Bug 187057 has been marked as a duplicate of this bug. ***
Just to add to what Harold said: PulseAudio enables all these features. I believe the latest KUbuntu defaults to using PA these days and has integrated all the patches necessary to support PA properly in Phonon and KMix. All these patches are now upstream so will be part of KDE 4.6 without any additional patching by the distros. I created a Wiki page in March to show how things should look like when everything is setup correctly. http://pulseaudio.org/wiki/KDE and here is a little YouTube video showing per-application volume control working, all the way through to the application level volume GUI too! http://colin.guthr.ie/2010/04/slide-around-the-sound/ And I even wrote a 5.1 Speaker configuration system for KDE 4.6 too: http://colin.guthr.ie/2010/07/speaker-setup-now-or-forever-hold-your-peace/ It could do with some GUI love, but the functionality is there :D @KaiUweBroulik2, if you have specific problems with headsets etc. under PA, please let me know and I'll investigate - the bugs don't fix themselves :D
