SUMMARY When I run the skrooge flatpak, the console shows a warning ##WARNING: Audio notification requested, but sound file from notifyrc file was not found, aborting audio notification and there are no sounds. Searching for "flatpak" and this warning message suggests that the marble and kdenlive flatpaks also don't play notification sounds, but I haven't reproduced this problem with them. STEPS TO REPRODUCE 1. flatpak install org.kde.skrooge 2. flatpak run org.kde.skrooge 3. Click Accounts, create an account (choose any bank icon, enter Account "test" and Number "1234" and click [+ Add]). OBSERVED RESULT The following appears at startup in the terminal: ##WARNING: Audio notification requested, but sound file from notifyrc file was not found, aborting audio notification And when you perform operations that normally play a happy sound, there's no sound. EXPECTED RESULT No startup warning, and sounds. skrooge.notifyrc specifies Sound=Oxygen-Sys-App-Error.ogg Sound=Oxygen-Sys-App-Negative.ogg Sound=Oxygen-Sys-App-Message.ogg Sound=Oxygen-Sys-App-Positive.ogg strace shows the flatpak app tries to access these sounds from $HOME/.var/app/org.kde.skrooge/data/sounds/ /app/share/sounds/ /usr/share/sounds/ /run/host/share/sounds/ and they're not available in any location, hence the warning. In Fedora, these files are in /usr/share/sounds/ . They are supplied by the oxygen-sound-theme package, 2 MB of files, so maybe that package should be part of the KDE runtime the same way /usr/share/sounds/freedesktop/stereo/ files are in the KDE runtime. SOFTWARE/OS VERSIONS flatpak version 1.4.1 Linux/KDE Plasma: (available in About System) ^ from `flatpak run --command='kdeinit5' org.kde.Platform --version` KDE Plasma Version: n/a KDE Frameworks Version: 5.12.4 Qt Version: 5.59.0 ADDITIONAL INFORMATION I tried working around the problem by copying the four .ogg files mentioned in skrooge.notifyrc into /var/lib/flatpak/runtime/org.freedesktop.Platform/x86_64/18.08/active/files/share/sounds but they didn't show up in the flatpak; I'm not sure how the "host" directories are mounted. I then tried copying the sounds into $HOME/.var/app/org.kde.skrooge/data/sounds/ , which avoided the WARNING about sound file not found, but... I didn't hear any sound, even with `flatpak run --socket=pulseaudio org.kde.skrooge`. FWIW kdenlive.notifyrc references two of the same sound files, plus a fifth, Oxygen-Sys-Warning.ogg.
I've retitled this bug to make it about adding the Oxygen theme sounds to the KDE Platform flatpak runtime. The KDE Platform has other sounds in freedesktop/stereo and Oxygen icons in plasma/desktoptheme/oxygen , so (by set theory ;-) ) /var/lib/flatpak/runtime/org.kde.Platform/... should include the sounds from the oxygen.git repository as well.

BTW another way to test sound in Skrooge is open Settings > Notifications, choose a notification, and click the [▶] play button.
