you can send a digital audio signal over CAT5, but the D/A at the other
end will be using a protocol that you almost certainly cannot implement
in software.

think about it: soundcards which send a digital signal out to the world
for subsequent conversion to analog have *hardware* to convert the
sample stream into a bit pattern on the wire.
