Odd audio autput trigger issue
When changing values of effects applied to a video strip there is a audio output triggered as if scrubbing the timeline.
Here is an example.
Even minimizing or maximizing the kdenlive window triggers the audio output. This is the only application that does that when minimizing/maximizing its window.
Tested with kdenlive-19.12.0-RC-x86_64.appimage on kde neon.
