SUMMARY I encountered an issue where KDE sound panel breaks (I can't change the default devices anymore, click on the the dot in the settings panel doesn't work and if I do in the tray icon mini panel, it shows toggles it on in the UI ,but keeps the old one also one and doesn't actually switch. It worked fine until yesterday, not today, no idea why. https://paste.gloriouseggroll.tv/?2589816ba506a11c#D5CNAZwdvtxrSJwgvx3jGKEwJdvhd7qAEQeqeXSashiL STEPS TO REPRODUCE 1. Connect more than 1 audio device 2. Try to switch in the audio device in the audio panel or audio settings OBSERVED RESULT In panel checkbox appears ticked on any device I've clicked on, old ones stay on, device doesn't change. In sound settings, when I click on device checkbox, nothing changes EXPECTED RESULT It works SOFTWARE/OS VERSIONS ``` ❯ fastfetch -l none OS: Nobara Linux 41 (KDE Plasma) x86_64 Host: ROG Strix G733ZW_G733ZW (1.0) Kernel: Linux 6.13.5-200.nobara.fc41.x86_64 Uptime: 15 mins Packages: 3411 (rpm), 23 (flatpak-system), 32 (flatpak-user) Shell: zsh 5.9 Display (BOE0A69): 2560x1440 @ 240 Hz (as 2048x1152) in 17" [Built-in] * Display (MB16A): 1920x1080 @ 60 Hz in 16" [External] DE: KDE Plasma 6.3.0 WM: KWin (Wayland) WM Theme: Breeze Theme: Breeze (Nobara) [Qt], Nobara [GTK2/3/4] Icons: Papirus-Dark [Qt], Papirus-Dark [GTK3/4] Font: Noto Sans (11pt) [Qt], Noto Sans (11pt) [GTK3/4] Cursor: breeze (24px) Terminal: konsole 24.12.2 CPU: 12th Gen Intel(R) Core(TM) i9-12900H (20) @ 5.00 GHz GPU 1: NVIDIA Geforce RTX 3070 Ti Laptop GPU [Discrete] GPU 2: Intel Iris Xe Graphics @ 1.45 GHz [Integrated] Memory: 7.24 GiB / 31.00 GiB (23%) Swap: 0 B / 42.09 GiB (0%) Disk (/): 218.35 GiB / 918.20 GiB (24%) - btrfs Disk (/mnt/ssd2tb_linux): 1.00 TiB / 1.79 TiB (56%) - ext4 Local IP (wlo1): 192.168.1.49/24 Battery (GA50358): 100% [AC Connected] Locale: en_GB.utf8 ``` ADDITIONAL INFORMATION I'm observing this on 2 different computers (both running same OS and all available updates installed)
Something extra to note, one of the computers is clean install on friday and encounters the same issue. I did try dowgrading pipewire wireplumber (using dnf downgrade pipewire wireplumber).
One more update, what seems to do anything is right clicking on the audio device in the sound panel and choosing play all audio via this device (same with mic).. It doesn't toggle the device visually but at leasst seems to change the actually used device https://i.imgur.com/azjhYvl.png
Found what was causing the issue, it's com.dec05eba.gpu_screen_recorder flatpak as strange as it is. Uninstalling that fixed it for both computers. Will report the issue to it's author also (and link to this issue)
