AFAIK older CD-ROM drives contained an internal DA converter and have been able
to output analog audio via a front plug to a e.g. headphone and via a rear cable
to the analog input of the soundcard. Furthermore an application was able to
read the digital signal from the drive directly and send it via software to the
soundcard but the reading speed often was too low and the process wasn't
reliable enough. Therefore in those years normally the sound was routed from the
analog output of the CD drive via cable to the analog input of the soundcard and
from there to its analog output. Software could start, stop, ... the drive but
did not handle the audio data stream.
Modern drives have economized the internal AD converter and the plugs. You are
not able to connect a cable. All software has to read the media's (CD, DVD)
digital content and send it to the soundcard. Reading speed now is fast enough
to handle the data stream reliable.
I have never seen (heard about) an optical connection between drive and soundcard.
