Use the i8042-filter to check if Volume key presses are also reported via atkbd and if yes then filter out the WMI events to avoid reporting each key-press twice. Note depending on in which order the PS/2 data vs the WMI event are handled the first volume key press may still be reported twice. This is a compromise versus DMI quirks (unmaintainable) or other more complex solutions.
