I believe the professional solution to this problem is an external DAC
which connects digitally to a sound card.  I know my uncle who owns a
recording studio has such a setup, 16-channel input to an external
DAC which connects into a single sound card through what I believe
was 4 Toslink channels (might've been AES/EBU, I don't remember exactly)
