It's only a matter of the drivers, that's it
Right. I wish it was this easy!
Feeding 16-bit audio into the 24-bit drivers ain't going to help a lot, although the 32-bit Hifi modes actually let the drivers do the scaling, so there would be some benefit. For true 24-bit usage, the applications need to change as well if you want higher quality recordings and edit them in 24-bit. A change of the drivers will not solve this by itself.
Kind regards,
