SUMMARY As the title says, the latest flatpak doesn't have any sound. VLC (flatpak) does, so I don't know what's the cause. Mpv also had an issue like this but now works fine. The only errors in terminal are F: Not sharing "/usr/share/icons" with sandbox: Path "/usr" is reserved by Flatpak Cannot load libcuda.so.1 KFileFilterCombo::setCurrentFilter() : KFileFilterCombo::setCurrentFilter: Could not find file filter KFileFilter(MIME patterns: QList() File patterns: QList("*") label: "All Files") The Haruna rpm segfaults when trying to start, so this issue seems to affect only the flatpak STEPS TO REPRODUCE 1. Get Haruna from flathub 2. open a video file with audio OBSERVED RESULT no sound is played, but the video does EXPECTED RESULT sound also plays SOFTWARE/OS VERSIONS Operating System: Fedora Linux 41 KDE Plasma Version: 6.2.5 KDE Frameworks Version: 6.10.0 Qt Version: 6.8.1 Kernel Version: 6.12.10-200.fc41.x86_64 (64-bit) Graphics Platform: Wayland Haruna 1.3.2 (from flathub) flatpak 1.16.0
Hi - do you have an NVIDIA graphics card on your system? If so, do you have the proprietary drivers installed in your base system, and do you have the user-space Flatpak runtime components (org.freedesktop.Platform.GL.nvidia-565-77 for the latest RPMFusion-distributed drivers) installed?
No, my laptop only has an intel igpu (lunar lake). I'm using the xe driver. Also sound used to work, then one day stopped. There were some updates which were made before with discovery (maybe they were related?), but dnf history can't list them
First check that the app is not muted in the volume applet. Otherwise try to rollback the Haruna flatpak to an older version https://itsfoss.com/downgrade-flatpak-packages/ see if you get a version that works.
sound is not muted either in haruna or KDE I tried to downgrade until 1.3.1 as this version surely worked at that time, but now it doesn't
well this is embarrassing, but turns out it was muted in the app window, which is why sound was working fine in other apps and Haruna's own volume slider was showing that sound was enabled. I'm not sure how it persisted across reboots and reinstalls and deleting the data, but now it works fine
