[Andrey Skvortsov]

Package: pitivi
Version: 2023.03-2+b1
Severity: important

Dear Maintainer,

on my system pitivi doesn't run:

```
$ pitivi
Missing soft dependency:
- GSound not found on the system
    -> enables sound notifications when rendering is complete
Missing soft dependency:
- cvtracker GStreamer element not found on the system
    -> enables object tracking
Missing soft dependency:
- librosa not found on the system
    -> enables beat detection functionality
