Kogan Mechanical Keyboard Macro Help

Hello fellow Kogan Mechanical Keyboard owners,

I am after some assistance with creating a macro with the Kogan Software.

I want a macro that allows me to switch between my Headphone output and Speakers output in Windows 10. I know I can easily do it from the taskbar but was hoping a macro might help during games etc.

Im trying to use the Kogan Software but cannot work out how to actually create this and assign it to a key (e.g FN plus - or something)

I have tried recording a macro to change the output, but it doesnt seem to work.

Can anyway with this keyboard provide any assistance and step by step guide or let me know if this is even possible?

Thanks so much!
