Bug ID: 495052
Summary: Multiple icons used for a muted microphone
Classification: Plasma
Product: plasmashell
Version: 5.27.11
Platform: Kubuntu
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Microphone Indicator
Assignee: plasma-b...@kde.org
Reporter: dev...@web.de
CC: k...@privat.broulik.de
Target Milestone: 1.0
SUMMARY
This is something that has been present since forever and never made sense to
me:
It can make a difference if you mute your microphone using a globally
configured shortcut
(in my case `System settings > shortcuts > audio volume > mute microphone = alt
m`),
or if you mute it using the GUI (clicking on the microphone or `right-click >
mute`).
When you mute it using the shortcut, it seems like the microphone enters a sort
of pseudo-muted state:
It is shown in the microphone indicator itself as `volume set to 0` (not
strike-through), however in the audio indicator it is shown as muted (muted
symbol, and the volume is kept as it is without being 0).
When you mute it using the mouse, the icon is loaded correctly as
strike-through.
On a related note: If my guess is correct, this extra state might also cause
another bug:
When you change the mute state, a "new microphone state" icon pops up in the
center of your screen.
However, from time to time, the icon displayed there de-syncs from the icon
displayed in the indicator (i.e. I muted my microphone and the icon it shows is
"microphone enabled" or vice versa).
If this seemingly extra state causes it, it would explain why the icon
sometimes de-syncs (or even re-syncs itself) without a clear indicator why
POSSIBLY RELATED:
https://bugs.kde.org/show_bug.cgi?id=398974
(which also shows how long this bug already exists if both refer to the same
issue - it seems at least somewhat likely)
STEPS TO REPRODUCE
1. Mute icon with global shortcut, observe icon
2. Unmute with same shortcut
3. Mute icon with the GUI, observe icon again
**Or any other combination of the two**.
The worst thing: It is non-deterministic which icon will be chosen when muting
using the shortcut:
I've managed both to get the correct "muted" icon as well as the incorrect
"volume is 0" icon while writing this bug report.
I assume that it depends on when exactly you mute/unmute the mic using the UI
that you switch states.
I think the only reproducible setup to get rid of these states is rebooting
your PC beforehand.
My experience so far is that on a freshly booted system, the incorrect icon
appears for muting via shortcut.
As stated above, once you are in the "wrong" (fixed) state, it doesn't occur
anymore - for a while.
OBSERVED RESULT
**Sometimes**, the icon differs.
EXPECTED RESULT
A muted microphone always receives the same icon, no matter how it was
triggered.
