linear pc power supply?

Fiber is not rated to 192KHz, a lot of receivers don't support it either (96K max).

For cheap onboard soundcards though, it's a boon as those don't have a transformer at the output, so the optical is the only thing that provides some isolation.

Fiber is routinely used for data rates in the gigabits, so even high bandwidth audio is nothing for a fiber.
Designing a laser diode driver and photodiode LNA that can handle the high speeds is not exactly trivial, but definitely possible.
