Of course a series like 0.707 0.707 0.707 will never arise unless the frequency is exactly half the sampling rate which is impossible.Also how does the D/A convertor know that the original was a sine wave when the only information its got is a numerical voltage value?
Its easy for you because you got prior knowledge, there are no such luxuries for the convertor. Could have been a sawtooth, ramp, triangle or square wave.
Or worse still a complex, non repetitive audio signal.
