The S/PDIF is serial digital, and I think it has chips available that go 
to/from rs-232c, as well as having D/A and A/D converters on some of 
them. I am *guessing* price of such chips to be about $30, and probably 
include the connector...more of a hydrid module than pure chip (I have 
only shopped for connectors, not modules, but I seem to recall seeing 
references to such hybrid modules). Some URLs that might be of use:

At the time I was looking into this, I was musing over the possibility 
of using the optical in on some sound cards as an advanced joystick and 
input device interface (that can record flight simulations or other 
control inputs as an audio file for later playback, especially in 
conjunction with animation software), or else just incorporating the 
connectors and standards directly with bare-bones hardware (I believe it 
would work, but I have no money to experiment with).
