how is digital sound created?

This is like, imagine the OP asked how does the analog signal turn into sound? The answer is, the analog signal goes through a voice coil, creating a magnetic field that pushes the coil in and out, which makes a cone go in and out, which moves air, and that makes sound.   

But instead of that we get lots of stuff about ports and crossovers and amplifiers. All very good to know. If only it had anything to do with the question.....   

It’s all part of error correction, all part of the Reed-Solomon code, and I actually quoted the exact math that applies.

If you're claiming that interpolation is all part of R-S coding that wouldn't be correct. Interpolation is specific to audio and R-S codes get used in plenty of applications beyond audio where interpolation would be inappropriate.

I don't know how it could possibly have been more clear that we are talking about digital audio here.
