When you convert that digital sound sample back to analog, there is mathematically only one smooth analog waveform (within the frequency limit) which passes through all the infinitely-short measured digital samples. it is a series of infinitely-short samples at intervals in time. And since a stairstep looks very different from a smooth analog waveform, it must sound different. People make this mistake because they think digital means the waveform is a stairstep pattern. As those frequencies are beyond what any human can hear (except maybe some newborn babies), the two analog waveforms will sound identical. The analog waveform produced by sampling at 44.1 kHz and 43.2 kHz are identical, except the 44.1 kHz waveform contains some slightly higher frequencies in the 21.6-22.05 kHz range. This is a common misconception about how digital sampling works.
