With my AMD radeon card the basic windows drivers work OK, the card's name is even mentioned in Device manager. Deinstall it and let windows install it's own on reboot. (In my case i use Widows 10).

Kent's suggestion is a good one, i hope that does it. However i never had any issues due 'set' sample frequencies in Windows 10 (and 7 Ultimate before that). I use 44.1kHz mainly, thought occasionally i work with Adobe Premiere, and 48kHz audio. No problems with that. But i have a more modern RME interface, and merging realtime automatic sample frequencies & converting from the inputs might be a piece of cake there. You might be off better with some modern audio interface. My old M-Audio 1010 was a good one, alas my current MOBO did not have a PCI slot anymore, only PCIe.
