We haven't given up on anything... The drivers work fine (the last time we looked).
When things are working correctly, WASAPI will in fact let you use speeds that aren't listed in Windows Audio Properties (for example 384k) However, when Windows only shows those two sample rates in Control Panel, it usually means a USB hardware negotiation problem. (In which case WASAPI won't be able to use them either.)
The most common reasons for this are:
1) Your USB cable is too long; the DC-1 and XDA-2 strongly prefer a USB cable that is two meters (6 feet) or shorter. (Some cables up to 3 meters, or even longer, MAY work, but they may not.) If you use a longer cable, you may well only see some of the available sample rates (like 44k and 48k.) Try a shorter cable.
2) Your USB cable is weird. Really old USB 1.0 cables don't work well at all (they aren't marked; but any reasonably recent cable is USB 2.0). Some "audiophile" USB cables simply don't meet standard - even some amazingly expensive ones - and so don't work (try a normal one - like one of ours or an Amazon basics one).
3) You should be connected directly to the computer - not through a hub (some hubs work; some not). Likewise, we assume some "extender cables" work; some definitely do not. Some ports on some computers work better than others; front and back ports are often different.

I have two PCs at my desk with a USB switcher between them for the DC-1, so I'm probably more like 3 meters total, with a run from each PC to the switch, and then on to the DC-1. Works great fortunately. The switch is an inexpensive Monoprice USB switcher which I only use for the DC-1. I first tried using a port on my keyboard, which is also switched on a separate KVM switch, but the DC-1 sees tons of noise that way. The DC-1 has to be isolated from all other possible USB traffic.
I have shelved my DC-1 for quite awhile and it was working fine before with my laptop when it was win7 and win8...now it is on win10..I checked that I have Fall Creator Edition and based on the document provided by emotiva..I do not have to install any drivers..but the thing is..my laptop cannot see the DC-1..it says Unknown USB Device..my source for the DC-1 is always the laptop..I also use the USB cable from Emotiva..I don't know what to do anymore..I already tried earlier installing the drivers but it cannot detect the CMEDIA device (DC-1)..I hope someone can point me in the right direction..I will still try to search solutions
