I’ve seen people ask many times why an application doesn’t have sound anymore. I’ve had it multiple times. The answer is always, go to sound settings in desktop mode, open the Applications tab and unmute the application there. But how did it get muted in the first place?
I feel so stupid, but the answer is so simple that I wonder if most people don’t already know it. You can mute/unmute an application by clicking the top-right area of its icon on the task bar. In handheld, I think this is so small that I didn’t notice it, but finally I did.
I’ve wondered for a while now how some applications got into this muted state. This probably also explains why clicking an application’s icon sometimes seemed to do nothing, as if the application froze. Instead, I was just muting and unmuting it!
I believe there is a setting to disable showing the volume on applications open in the taskbar in the settings app (naturally, in desktop mode).
Or it might be an option after right clicking the taskbar. Can’t recall which one it is.
Disabling this should prevent you from being able to mute them accidentally in the future.
There’s a volume mixer extension for Decky that might let you fix muted applications from desktop mode.
