Sometimes for no reason on KDE 6, the audio icon would go haywire and show that my audio is muted. Whenever I interact with the audio (mute and unmute) the indicator goes back to normal before it indicates my audio is muted again.
Basically, the audio is fine but the audio indicator is bugging out and keeps saying that my audio is muted when playing no audio.
I think I’ve only experienced this twice in a month or two. Extremely rare case.
