Sorry for popping this up back but I've been researching my problem with XMOS drivers that are "the only ones we have" (c) Klipsch. So, only thing is that those XMOS drivers are signed but the signature is already out of date. I agree that Microsoft provides good drivers for listening music, nothing huge there. Still, I was baffled that I cannot get drivers provided from company like Klipsch while there's so many quite small companies who still try to get most of their equipment with frequent driver updates.
So, only two options are on the table if you want to use Klipsch's "only drivers they have to provide" (even if they could just update their signing on the drivers, phew): A) you use your product without control panel (for example buffers etc.) and just use what Windows provides after you have fixed the DFU warning in the device manager B) you have to disable Secure Boot from your BIOS and only after that it's possible to use the option seven in boot options to disable Signature Enforcement, install drivers and use them.
I got them working like that but while being pretty precise about my security options while using Windows, I just had to swallow my XMOS fantasies and continue using the Microsoft drivers and they are good for listening music don't get me wrong, for music production and well, using the options I should have in my hands when having this product on my table, they are not available.
Just to inform people who are about to buy this product and use it under Windows 11 with Secure Boot enabled which I guess is required to install it in the first place (don't know about earlier Windows versions).
