SUMMARY In Plasma 5 clicking on the audio icon of an application in the task manager would mute ONLY that application. With Plasma 6 (Fedora 40), the behaviour has changed, erroneously I believe, to muting ALL applications. The original feature was added through this submitted patch: https://phabricator.kde.org/D19822 STEPS TO REPRODUCE 1. Open more than one application that outputs audio 2. Click on the audio (speaker) icon in the task bar to mute ONE application OBSERVED RESULT All applications are muted. EXPECTED RESULT Only the application that was explicitly muted should be muted. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora Linux 40 (available in About System) KDE Plasma Version: 6.1.0 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.1 ADDITIONAL INFORMATION
As always seems to happen after an hour of testing, but mere moments after submitting the ticket, I've noticed that this behaviour happens under a specific circumstance. The application I had been muting was a game launched through Steam (Hitman Go), the behaviour described occurs if you mute this specific application, but not when muting other applications (so far). I can individually mute the game through pavucontrol or kde sound settings, and muting it through the task manager has worked in previous plasma releases but there's obviously something specific to the way audio is routed for this game which is causing this issue in Plasma 6.
When you mute the game through it's task manager icon, what other apps get inappropriately muted as well? Can you paste the output of `pstree`?
(In reply to Nate Graham from comment #2) > When you mute the game through it's task manager icon, what other apps get > inappropriately muted as well? So far, every application I've tried - VLC, Elisa, Google Meet app (Electron), Audacity and ffplay (launched from Konsole). I don't have audio notifications enabled so I'm not sure if they are similarly affected. > Can you paste the output of `pstree`? $ pstree systemd─┬─ModemManager───3*[{ModemManager}]

Thanks. I was hoping it would be obvious because they all had the same non-systemd parent process or something, but no dice. Are you also seeing an issue whereby when one app is playing, all of them erroneously get mute badges in the corner?
(In reply to Nate Graham from comment #4) > Are you also seeing an issue whereby when one app is playing, all of them > erroneously get mute badges in the corner? No, only the apps currently playing audio shows the speaker icon. When muted individually when muted only the muted app shows a muted icon. When the game is muted however, all apps which were currently playing display the mute icon. In other words this behaviour is at a high enough level that the icons correctly reflect the application status. This is distinct behaviour from say muting line out which isn't reflected in the task manager icon.

Well, that's confusing. No idea what to do about it, and can't reproduce it on current git master with any of those apps or some Steam games.
