2021 Blade 15 Advanced OLED

Hey all... I recently got the above, it's branded with a THX Spatial Audio sticker yet the Razer THX Spatial Audio App was not installed, only the THX Spatial Audio app which I believe you can get from the Microsoft store. Anyway, when I launch the THX app I get a message saying 'Digital Headsets are not supported at this time and to please connect 3.5mm headphones blah blah blah... which is odd? This is cr*p as I use a USB DAC!! So I found the Razer Spatial Audio App where digital headsets ARE supported.... and it's £19.99!!, so basically you spend over 3k on a laptop that doesn't even come with all the Razer software? Or can I obtain a licence from support? Just wondered if anyone else has encountered this? Cheers!
