Har du adgang til en PC med Windows 7? For så prøv lige at sætte headsættet til den først og så i Windows 8 maskinen bagefter.
Google fandt nemlig denne mulige lappeløsning:
"Actually the problem is with the firmware that is embedded on the PX22 volume control hardware. To fix the issue of Windows 8.1 not recognizing this headset, plug this headset into a Windows 7 PC. This will jog the firmware. Once the Windows 7 PC recognizes this headset, you can plug it into a Windows 8, 8.1 PC. This only works for a while - until reboot - or if you lock your Windows 8, 8.1 PC for too long - you will have to plug this back into the Windows 7 PC."
