            Bug ID: 509695
           Summary: kcm_pulseaudio profile selection allows lockout of
                    devices without a hard wireplumber refresh
    Classification: Applications

Suggestion for where to add the hard reset button (could shift everything over
to the left, and have this be the top-right button)

SUMMARY
When configuring audio devices via
systemsettings kcm_pulseaudio
, you are able to select a profile for a device which it cannot support

STEPS TO REPRODUCE
1. $systemsettings kcm_pulseaudio
2. Select any audio device, and open the 'Profile' dropdown for it
3. Change it to something absurd for that device

OBSERVED RESULT
Naturally, this causes the device to be, for all intents and purposes, unusable
for what it was built for. 

EXPECTED RESULT
A button present that will perform a "hard reset" on all audio devices & their
profiles, allowing a "from scratch" re-detection of everything, which would fix
even the most egregious user UI errors (might be as simple as running the
commands in my WORKAROUND section :) )

SOFTWARE/OS VERSIONS
KDE Plasma Version: 6.3.6
KDE Frameworks Version: 6.13.0
Qt Version: 6.8.2

ADDITIONAL INFORMATION
WORKAROUND (This removal command may be a little too general, but depending on
what the user has misclicked, might be necessary):
$rm -fv .local/state/wireplumber/
$systemctl restart --user wireplumber

This should reset all audio device profiles to their defaults, and pipewire
should auto-detect their ideal profiles. You will have to re-adjust volumes /
captures for some of them, and restart certain apps (Chromium and Electron apps
espeecially struggle with this), but you get your audio back
