So if I wanted to design a sound card (for a hobbyist retro-future-pc), what kind of sound card should I build?
Something classic FM synth like a Yamaha OPL? Something useful for modern formats, like the VS1053b? Some bare/raw DAC?
Retrocomputer and other friends, opinions?

Or maybe more about algorithms if you already have a DAC. FM can easily be done on the chip you're using.
If you don't have a DAC or don't want to use one a combination of PWM and software Sigma-Delta is possible also. (S-D also possible with DAC to increase resolution).

From a usability p.o.v. I'd skip the FM and go with a sample player. Think Amiga tracker.
