SUMMARY For example when I bake bread there are 3 timings with different temperatures in the oven, for which this alarm would be excellent to remember me instead of burning it. Sadly everytime I use it and watch a video fullscreen, the sound that should be played either doesn't play at all or is muted. If I only work on desktop, the alarm works fine. Is it a problem with Wayland or Kalarm? Haven't tried X11 but also the Timer widget, that doens't work either. STEPS TO REPRODUCE 1. Set alarm with sound 2. watch Youtube fullscreen 3. wait for alarm OBSERVED RESULT nothing EXPECTED RESULT sound SOFTWARE/OS VERSIONS Betriebssystem: openSUSE Tumbleweed 20250627 KDE-Plasma-Version: 6.4.1 KDE-Frameworks-Version: 6.15.0 Qt-Version: 6.9.1 Kernel-Version: 6.15.3-2-default (64-bit) Grafik-Plattform: Wayland Prozessoren: 16 × AMD Ryzen 7 7735HS with Radeon Graphics Speicher: 32 GiB of RAM (28,1 GiB usable) Grafikprozessor: AMD Radeon 680M Hersteller: AZW Produktname: SER Systemversion: Version 1.0
Created attachment 182823 [details] KDEBugTriage_Kalarm_Bug 506398 Screenshot taken when YouTube was playing a video at full screen and a alarm was set in the KClock application.
I am not a KDE developer. I am trying to do a KDE Bug Triage (https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging) I do not have Kalarm installed. On using KClock ver 25.04.2 installed the alarm set a notification is displayed and sound is played when playing a video in full screen. Please see the attached screen shot, "KDEBugTriage_Kalarm_Bug 506398" for more details. However on using KClock ver 25.04.2 and a countdown timer being used, instead of a alarm, a notification is not displayed, when timer is up, but a sound is played. The YouTube video was being played in full screen on Mozilla Firefox browser ver 140.
On my development system, which is less up to date than your system (KDE Frameworks 6.8.0 and Qt 6.7.2), when I play a YouTube video fullscreen in its QEMU virtual machine, KAlarm audio alarms play as expected under both X11 and Wayland. The Timer widget also works on Wayland with fullscreen YouTube. I don't know whether the fact that the fullscreen video is running inside a virtual machine could perhaps affect what happens (although I don't see why it should), but unfortunately I don't have a suitable system to test a recent Wayland on a standalone computer. The fact that both KAlarm and Timer don't work for you does however suggest that it's a system problem and not a fault in KAlarm or Timer. I'm reassigning this bug to kwayland (I hope that's the correct product) since it seems that it might be a Wayland issue.
