This happened after I changed from ALSA to PA, saved, then mousewheeled over the icon;

Does this only happen after the mouse wheel commit (could you please try reproducing it with the previous commit)?
Unrelated: which panel do you use for the systray?

[redtide]

Still present after replacing QSystemTrayIcon with the SNI library, but the issue is about a nullptr for an AudioDevice instance (device.hpp L50, volume() getter).
This crash doesn't happen if changing volume from the slider, which does nothing.

Forgot to reply before: fwiw; the notification area systray that's integrated in AwesomeWM. (Also fwiw, afaik, Polybar is probably the most used bar app, given most X WMs don't have an integrated bar)

[redtide]

I heard about it, but not tried, still using X11 on Openbox, I'm waiting for LXQt to support Wayland on next release, then switch WM to LabWC and continue to use lxqt-panel.
I see this module, see polybar/polybar#913 and polybar/polybar#2010

The problem is the configuration dialog saves the index of the combo as the engineId, which isn't always true.
In my case, the combo has ALSA and PulseAudio, so it saves 1 if I select Pulseaudio, which is OSS in engineid.hpp.
If I manually write EngineId=2 in ~/.config/qtilities/VolTrayke.ini it works.
