The CD Audio ports on the card are labeled Sony, Mitsumi, and Panasonic. Does this mean that I need a compatible drive from one of those brands for CD Audio to work, or is one of them also plain-IDE compatible, or can I use any one of the ports?

The CD-AUDIO inputs are wired in parallel to each other. They do the same thing.
The sony one has a different shape and pinout because sony...
The other 2 ones also share the same signals but have a different pinout.

if i look at the back of the card : the sony connector is Signal|GND|GND|Signal , Mitsumi is Signal|GND|Signal|GND , and Panasonic is GND|Signal|GND|Signal

In this case IDE has nothing to do with it. The manufacturer of your cd drive decides the pinout for Audio...

Your CDR-273 seems to use the Sony pinout with GND on the 2 center pins.

Now you need a cable that either is a 1:1 sony style , or a different cable wich adapts pne pinout to another pinout/connector.

Many thanks!

It seems I might not have a cable on hand for this. It might be difficult to source the proper cable due to age, or maybe I can modify one.

Perhaps this? It is universal with the classic drive brands:

That is a pretty expensive cable...
But yes it works.
You can always take any cable that has fitting connectors and repin the connectors if even needed.
I just use a needle for repinning.

Thank you! I wish I had a suitable cable lying around. I need a floppy-style connector on the sound card end. I want to say that I used to have a cd audio cable with multiple ends, but I probably lost it along with many other parts during a move or two, over the years.

I don't think I can use that, after all. The cd-drive end on my NEX is like the more modern versions. It even has that two pin jack next to the 4 pin jack.

I tried the same cable that my AWE32 was using with the NEC quad speed. It works with the Panasonic port, so I don't need to buy that expensive cable! I still need to find a way to test to make sure that the left/right channels are not switched. However, I now need to find another one just like the AWE32 cable, since I am putting it in a P3 system to use with Moslo Deluxe to emulate a Pentium 166 with a Voodoo 3, a Voodoo 1, and Windows 95 OSR2.

My 486 with "my very first sound card" is almost complete, hehe!
