It is better to only play sound when the mouse click is released , not by any changes .
In fact, the best way to do this is when releasing a mouse click , looking for any media in play , if detected any media in play the Volume Controlمer does not need to play the plop sound because at that time any media is in play user can be hear the media sound and at that time the plop sound is annoying .
There's a patch that fixes this: https://phabricator.kde.org/D22316
Git commit a420dd6be1a9a5b51c50074ce9d09b77a0a5cbbe by Nate Graham, on behalf of Kezi Olio. Committed on 08/08/2019 at 16:35. Pushed by ngraham into branch 'master'. Avoid garbling the sound if the volume slider is moved fast Summary: The audio should not be garbled if you move fast the audio slider (it distorts because it stops and plays the feedback sound every few milliseconds) An alternative approach is to `return`; if the `ca_context_playing` says that the sound is still playing, but that gives less "resolution" Related: bug 409525 FIXED-IN: 5.17.0 Reviewers: #plasma, drosca, davidedmundson, ngraham Reviewed By: #plasma, davidedmundson, ngraham Subscribers: anthonyfieroni, filipf, ngraham, davidedmundson, plasma-devel, kezik Tags: #plasma Differential Revision: https://phabricator.kde.org/D22316 M +4 -4 applet/contents/ui/ListItemBase.qml https://commits.kde.org/plasma-pa/a420dd6be1a9a5b51c50074ce9d09b77a0a5cbbe
