hello! I am having driver installation problems for my SU8 DAC, I try to install the latest XMOS driver from the website and i’m getting a installation failure every time. then it asks to restart my pc. after the restart I checked the folder installation and nothing is there. this driver will not install. please help :c

I’d start with updating your audio drivers or reinstalling them after a full uninstall
