I hope we are not confusing sampling rate (number of samples per second) with bit depth (16-bit vs 24-bit vs 32-bit) - using a larger "word" size should not resample anything, should it, but would merely fit the top 16 bits up front into the 24-bit word, right? The extra bit depth is very useful for performing DSP calculations with greater accuracy

...I thought we were talking about sample rate conversion from 44.1 khz to 48, where the important thing is the math used when the number of samples at the new, higher, rate are not integer multiples of the number of samples in the rate being converted from, therefore some kind of interpolation must be used lest the new output show patterned errors and not fairly represent the original input to the best of it's ability. Separate issue from bit depth (16 vs. 24 vs. 32, etc.) Sure, increasing bit depth is as easy as adding zeros, then using whatever math to cut the sample down for volume control and the like.
I don't know if the k-mixer makes an audible difference in most cases, I've read reports of audible differences, but then I've read reports of people claiming to hear audible differences between digital cables, which I've never seen demonstrated in a blind test (and suspect I never will). I have read things that lead me to believe that it doesn't work properly for someone who wants nothing more than to pass exactly what's on a CD over a digital interface to an outside decoding mechanism. According to some documentation, k-mixer doesn't perform SRC if there is only one stream present and/or hardware mixing is enabled on the card.
