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.

simplescreenrecorder-2019-12-03_13.17.02

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.

Cheers :)
