1 bit is not actually outputting only 2 levels, it uses two levels of
output which is then filtered to make the waveform that's wanted.
8 bits produces 256 levels.

It sounds like you need to learn some basics first.
Optical output is pointless.
A 128 bit soundcard, if 0db(inaudible even in a quiet room) was set to be
1lsb, (at one meter) would at a billion billion billion billionth of
full power release as much energy as a supernova.
This is probably one reason why they are not available.
