Wow, that's great. But it seem to easy to be true :-) Do they really 
provide the delay between start of playing a buffer and start of 
appearing the analog signal at the output?

I use Hammerfall/Digiface with some attached D/A-Cs. Do the driver know 
what's the latencies of D/A-C, especially if connected to a digital 
sound card output, like mine? Or do the API just deliver the value what 
can be set in settings of the Hammerfall "Buffer Size (Latency)", which, 
unfortunately, is not the latency between the software layer and analog 

Tim, do you know whant latency do they provide?
