I am currently rebuilding a pentium 1/233 PC and try to find the right port to connect the CD-Audio cable.
It's either "Sony" / "CD-In/Mitsumi" / "Panasonic" or "Line in" ...

Following the cable connector it is probably either "CD-In/Mitsumi" or "Panasonic" (see pricture).
(The CD drive is something like an OEM CD-WRITER Plus 9xxx)

What do you think?!?!

Building my own PCs since 1991 - for my retro builds it's "no CF-disks, no Floppy emulators, no modern cases etc.", only the real and authentic stuff whenever possible.

The Mitsumi port should work and you can easily test it with an audio CD.

With luck, the pinout on the drive itself will be marked with R, G, L, and possibly O.

RGGL would be "Right, Ground, Ground, Left"; ORGL would be "Open (or 'not connected), Right, Ground, Left" and so on. I think the Panasonic input is RGRG (Right, Ground, Left, Ground), so you could just cut the cable and rewire it so the sound card end corrects the difference between those pinouts.

The CD audio is in millivolts so you're not going to hurt anything by just experimenting with the cable. Maybe play an audio CD track that alternates Left/Right, Left/Right (such as a test CD for home stereo equipment, or just burn an audio CD with such a track (even homemade with you speaking in a microphone).
