Bug ID: 507824
Summary: Audio mute toggle key (keyboard) doesn't always
correctly toggle mute/unmute status
Classification: Plasma
Product: plasmashell
Version First 6.3.6
Reported In:
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Audio Volume widget

Target Milestone: 1.0
SUMMARY
The keyboard's "mute/unmute" toggle key doesn't always correctly toggle the
muted/unmuted status
There are two ways to reproduce, (B) seems to be systematic, (A) is not. It
recently started happening to me pretty often, and just now I was testing and
reproducing consistently, in both the ways described below.
Then, as I came here to report the bug and was testing again, (A) started
behaving as expected. As I kept trying, (A) reproduced again and then again
not. Meanwhile (B) seems to always systematically reproduce.
STEPS TO REPRODUCE (A)
0. Start with the audio unmuted
1. press the Mute/unmute key on the keyboard to mute the audio -> audio gets
muted as expected
2. Press either the volume-up or the volume-down key on the keyboard. This has
the effect of unmuting.
3. Press the mute/unmute key on the keyboard
EXPECTED RESULT
This should mute again
OBSERVED RESULT
You hear the system sound that is usually heard when unmuting or changing the
volume, and the audio stays unmuted
STEPS TO REPRODUCE (B)
0. Start with the audio unmuted.
1. Mute using the mouse and the tray-icon widget
2. Press the mute/unmute key
EXPECTED BEHAVIOR: should unmute
OBSERVED BEHAVIOR: remains muted; next key press will unmute
Note: the following does NOT reproduce even when (B) does: (i) unmute using the
mouse and the widget, (ii) press the mute/unmute key. This always works as
expected, muting the audio.
Note: you might think that the toggle key remembers its own muted/unmuted
status, regardless of what the real status (I'm not saying the hardware
literally does it, I mean logically somewhere in the software), and isn't aware
of what happens to the audio when it gets muted/unmuted by other means other
than the key itself, and therefore it gets "out of sync" and sometimes seems to
work and sometimes doesn't depending on whether it's in sync or not, but that
is NOT the case. The observed behavior is not compatible with that explanation
(unless it _sometimes_ gets the information about the actual status changing
from elsewhere but sometimes fails to do so).
