I have not yet put the card in, but had a thought... The sound cards from that era, have a jack where an audio cable connected it to the CD/DVD drive. Where the card would override the on-board audio once installed, would that audio cable still be necessary today, or would today's motherboards know to route the audio from the CD/DVD through the motherboard, directly to the sound card? I haven't actually looked at the back of the DVD drive to see if it even has that connection on it. That system is from 2009.
I do not think modern drives have it - you can easily diagnose it by observing the front panel of the drive - if it has an audio jack, it can independently play audio.
Applications such as kscd would work with the data being read from the drive. I do not know why Kate would say kscd needs an audio cable. I guess kscd is able to control the drive (play/pause etc.), so that if
you
have a CD player you could just tell it play and listen on the audio jack of the player. However it should be working as a player too - playing the cdrom. Last time I tried few months ago it worked nicely.
The drive does not have an audio jack on the front.
kscd will control the hardware but it needs a optical drive to audio card audio cable to play the output. You can test it yourself.
I think Ed was talking about the back cable not the audio out front panel port some optical drive had.

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.
