So, I've gotten the opportunity to install DSL on my Panasonic CF-25 alongside Windows 95 and it works wonderfully. The only problem is that I'm missing sound. Supposedly, there is support for the OPL3-SA chipset, which the laptop itself has, but for some reason I can't seem to get it to work. I've tried configuring it any way I can, but to no avail. I even tried "modprobe sb io=0x220 irq=5 dma=1 type=4 isapnp=0" and it froze as soon as I tried playing a sound file. Any suggestions?

No luck. Says "no such device". Also, my model of the CF-25 has the OPL3-SA3 based chip, in which I've used OPL3-SA2 for that. It seems to go through just fine over the command line, but when I try and playback a sound file, it doesn't freeze, but it gives me a "couldn't open audio" error. I even tried to include "modprobe opl3sa2" in the boot config, but it doesn't load it on startup.

i was actually able to get ALSA up and running via MyDSL and did sndconfig in the terminal to set my sound driver as OPL3-SA2. Unfortunately, I still can't get any sound whatsoever. And yet, this computer works perfectly fine with sound in Windows 95.

Don't worry, it's not your fault. Sound in Linux systems never worked for me, either.
Around 2000 I tried to load SB16 drivers in KDE (?) and everything freezed when I enabled full-duplex mode.
Hasn't been getting better since then. PulseAudio kind of works, but always stutters on my PCs.
And in the rare moments things seem wo work fine, other issues appear. Like static noise during playback, mixer not working,
wrong mapping of audio channels (modem device), applications supporting only OSS but not ALSA, et cetera..
So yeah, it certainly can be done somehow, but it requires nerves of steel. 😉

with alsa you have to enable the sound, use the mixer, dont trust the labels in there

That's a big part of your problem right there. Pulseaudio is a known mess in modern Linux.
