This is true, but it's only one possible approach.  You can play the
CD, take the audio from the headphone jack and connect it to the audio
in on the sparc, digitize it, and send it to another machine over the
network.  Assuming its a novelty and not a serious need to get digital
accuracy for playing a CD over the network, that might be acceptable.
