Created attachment 181628 [details] Video showing bug SUMMARY In the KDE audio device selection interface, the radio button for the output device "UGREEN-70304" appears selected twice, while "Built-in Audio Digital Stereo (HDMI)" is not selectable. This visual bug prevents proper audio output switching. STEPS TO REPRODUCE 1. Switch audio outputs 2. 3. Operating System: Fedora Linux 42 KDE Plasma Version: 6.3.5 KDE Frameworks Version: 6.14.0 Qt Version: 6.9.0 Kernel Version: 6.14.6-300.fc42.x86_64 (64-bit) Graphics Platform: Wayland Processors: 32 × 13th Gen Intel® Core™ i9-13900K Memory: 94,0 GiB of RAM Graphics Processor: Intel® Graphics Manufacturer: ASUS
From the video, it appears that "UGREEN-70304" is selected *once* not twice *and* that clicking on "Built-in Audio Digital Stereo (HDMI)" selects that as well, so both devices are selected. The visual bug I see is that both the UGREEN and HDMI audio device radio buttons are selected, when only one should be able to be selected Clicking on the HDMI output should un-select the UGREEN output
(In reply to TraceyC from comment #1) Correct Also 1 Ugreen selected 2 click to HDMI 3 click to Ugreen (HDMI remains selected) 4 hit enter on keyboard: it unselects HDMI
I'm pretty sure I saw this yesterday on 6.3.5, but I can't reproduce today on that version or git-master. I'll leave this open in case someone else can reproduce.

Here is gdb core dump (gcore) gdb --args plasmashell -d --replace on breakpoint Sink::setDefault when the bug appers https://drive.google.com/drive/folders/14uJsbl0K6RDLNvy7xo8ggq8x5aMNjHsT

I was able to reproduce it with the latest neon-unstable-developer-20250512-0038 I have a QEMU VM with a snapshot during bug (CPU is set to qemu64) https://drive.google.com/drive/folders/14uJsbl0K6RDLNvy7xo8ggq8x5aMNjHsT virsh snapshot-create --domain linux2024 --redefine snapshot2.xml so coredump is deleted from gdrive
