There's not necessarily a DAC at "the end" anymore. Could be SPDIF
too.
And if you say that a modern sound card behaves very similarly to early
90's sound card because it ues DMA, then you could say that sound card
is very similar to a harddisk, too. Which is definitely true in a way.
The really interesting part of audio is not the data transfer, it's
the timing. And that's where hardware changed. And software too. And
OSS is broken and legacy.
