No sound/audio in KDE4 (SOLVED)

[Daniel Simon]

SOLVED!

The standard install of KDE4 through MacPorts uses Qt's phonon system, which in turn uses the native QuickTime as a backend.  As it states at http://mac.kde.org/?id=download , if QuickTime can't play it, phonon can't play it.

The solution is to install the Xiph (ogg) QuickTime component (http://www.xiph.org/quicktime/) to allow QuickTime to play ogg files.  Installing Perian (http://perian.org/) wouldn't hurt, either.

There should be a note during the port install process saying that this step is necessary since much of KDE's audio is in ogg format.

Happy KDE-ing!

I haven't been able to get the sound to work either.

All of the kdegames are silent.

If you do a "port search kde" you will see that all of the pertinent ports for kde 3.5 say, "No KDE sound support" in the description, so sound was obviously problematic with that version.

On the other hand, the kde 4 port descriptions do not say that.

Perhaps someone with more knowledge than me could tell us whether sound is supposed to work in kde4 or not?

Anyone?!

Has anyone gotten a KDE4 app installed that can produce sound?  Amarok?  How did you do it?

I tried installing kdemultimedia4.  Installed properly (without kmix), but no change in sound.

Tried installing phonon directly.  Installed properly, no change in sound.


Thanks,

I've installed kdegames4 and kdeedu4 successfully (the programs all run fine) but there's no sound/audio.

In particular, trying klettres from kdeedu4 produces no sound.  On the other hand, if I go into to the qtdemo application and load the phonon test app, I do hear the test sound.  So, QT can produce sound, but KDE can't.  I've looked in the logs in Console.app, but don't see anything when I try to call a sound from a KDE app.

I installed kdegames4 and kdeedu4 roughly following this protocol:  http://lists.macosforge.org/pipermail/macports-users/2010-January/018527.html

Anyone have any suggestions?

Thanks!
