Audio Effects Not Working in Kdenlive on Ubuntu 24.04

Help
1

Hi everyone,

I recently installed Ubuntu 24.04 and downloaded the Kdenlive Version 24.02.2 AppImage from the official Kdenlive website. For some inexplicable reason, most of my audio effects are not working. I can add them to the audio clips, but they have no effect whatsoever.

Here are the steps I’ve taken so far:

  • Tried using the Kdenlive version from the Ubuntu repository.

  • Tested older AppImage versions of Kdenlive.

Unfortunately, none of these attempts resolved the issue. Below, I’ve attached the terminal output I get when running Kdenlive. Any help or suggestions would be greatly appreciated.

Terminal Output:

I can confirm that. Since version 23.08.5, some audio effects that I use no longer have any effect. In my case, effects from the “EQ and Filter” group. My system is Ubuntu and I was able to reproduce the behavior with the .deb, Flatpak and Appimage versions. Since then I have been using Appimage version 23.08.4. I would be very happy if this could be repaired.
Best regards,
Marcus
