Bug ID: 521973
Summary: System tray volume icon shows muted speaker when USB
audio device is default sink
Classification: Plasma
Product: plasmashell
Version First 6.7.0
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Audio Volume widget
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: 1.0
DESCRIPTION
The volume applet in the system tray shows audio-volume-muted-symbolic
(crossed-out speaker icon) even though audio is working normally and the device
is not muted. This happens with a USB headset as the default audio device.
STEPS TO REPRODUCE
1. Connect a USB headset
2. Ensure it is the default PulseAudio/PipeWire sink
3. Observe the system tray volume icon
OBSERVED RESULT
Icon shows crossed-out (muted) speaker
EXPECTED RESULT
Icon reflects actual volume level (low/medium/high)

ADDITIONAL INFORMATION
In applet/main.qml line 84–85, when PreferredDevice.sink is null or is the
dummy output (auto_null), the fallback is:
: AudioIcon.forVolume(0, true, "")
This calls audioicon.cpp with muted=true, which always returns
audio-volume-muted-symbolic. USB audio devices can trigger this path during
plug/unplug cycles when PipeWire briefly loses
the default sink.
Suggested fix:
: "audio-card-symbolic"
This correctly conveys "no device" rather than "user muted audio", which are
semantically different states.
