I find that the best version to use on the Panasonic drives is either 5.3.2 or 5.4. On my 7.1 systems (I don't run 7.0, or anything below 7.1), I generally use a copy of the CD-ROM software lifted from a 7.6 system, which IIRC is 5.4.
However, none of this will allow you to play audio CDs over the internal speaker. In fact, no version of the Mac OS supported digital audio playback until OS 9, and i seriously doubt that the OS 9 Apple CD/DVD driver would work on anything below OS 9, let alone a Classic running 7.0.
Besides...why would you even want to listen to audio CDs on the internal speaker? You can get a cheap set of crappy external speakers for...well, nothing these days, and even that would sound miles better than the single speaker in the Classic, believe me. About 8 years ago I used to have a few audio CD tracks in AIFF format that I used to play on my Classic II from a Zip 250 disc, and it sounded absolutely horrible.
