I had bookmarked this page so I could test it "just for fun" (and to be helpful), mostly because it seemed like something I could easily test. I don't currently have any projects that need to play wav files with QML SoundEffect, so the outcome is not of immediate impact to me but (again) this seemed easy to paste into a QML file and launch. So (after a week's delay 😅) that is what I have done. My OS is Ubuntu 22.04.5 LTS jammy I generated the wav files as follows: sox -n -r 48000 -b 16 tone_1.wav synth 0.6 sin 440 sox -n -r 48000 -b 16 tone_2.wav synth 0.5 sin 240 When I launched the code using Qt_desktop/6.8.3/gcc_64/bin/qmlscene, things seem to work pretty well. I cannot reproduce the reported issue. I then tried with both: Qt_desktop/6.12.0/gcc_64/bin/qmlscene and also Qt_desktop/6.12.0/gcc_64/bin/qml In both of these 6.12.0 attempts, I hear no sound whatsoever! 🫤 So I still cannot reproduce the reported issue, but I definitely see different outcomes between 6.8.3 and 6.12.0, which the behavior in 6.12.0 seeming to be worse. (But maybe there is some other dependency I am missing to use multimedia in 6.12.0 on Ubuntu 22.04? .... but there wasn't any warning or error printed that would hint in that direction...) When I use 6.8.3 I see: qt.multimedia.ffmpeg: Using Qt multimedia with FFmpeg version 7.1 LGPL version 2.1 or later And with 6.12.0 I see: qt.multimedia.ffmpeg: Using Qt multimedia with FFmpeg version 9.0.1 LGPL version 2.1 or later

yep. really cool. will try later ... curious: years ago, as I switched from BlackBerry10 (Cascades/Qt 4.8) to Qt 5 (QuickControls2) I really missed the GroupDataModel from Cascades, where I could do things like this: import bb.cascades 1.2 ListView { dataModel: GroupDataModel { sortingKeys: ["lastName", "firstName"] sortedAscending: true grouping: ItemGrouping.ByFirstChar } } great to see what's now possible with Qt QML - THX :)

Thanks a lot for all this information. It has helped me get clarity on the questions that have been bugging me for weeks. I can now decide better what I want to do, and why. I will definitely share these with them ideas about unifying the UI for mobile and desktop with Qt, as it seems like it doesn't necessarily warrant replacing starting their application from scratch, only their UI code will get replaced (and its bindings).

This had been reported to Squish technical support team, and closed on behalf of the reporter. Unfortunately it was not possible to identify a clear cause so far.
