Being DOS based games, you need to know what the DMA & IRQ settings of your sound device is.
You will then have to enter the game setup menu, select the correct sound device (Sound Blaster Pro), the correct DMA or IRQ settings and save the settings.
Some setup programs can auto detect the above-mentioned settings for you.
You can also search for the Autoexec.bat file on your laptop's root folder and ensure that there is a Set Blaster environment variable listed.

Imho all you need is one line in autoexec.bat...

SET BLASTER=A220 I5 D1 T4

...and adequate settings in BIOS, see attachement 😀 It's from Libretto 50CT, but I quess 60CT is pretty much the same.

Thanks for the advice! I checked my BIOS and the only difference was SBPro DMA channel, I changed it to be the same setting as yours, added the SET BLASTER line to my autoexec.bat, but no go, still no sound 🙁
I even tried manually adding the variable to my DOS ENV to no avail.

I guess it could be muted by default or it could somehow get stuck in WSS mode.
Try UNISOUND: UNISOUND - Universal ISA PnP Sound Card Driver for DOS v0.81b

Unisound won't help, I tried it on my 50CT, no PnP card detected...

I've found some OPL3-SA drivers on the harddrive of my Libretto, I don't recall if I've ever used them, maybe they'll help 😀 See archive in the attachement. There are also some other utilities - TDIAGS for diagnostics, TSETUP for BIOS setup and TLCD for LCD brightness settings. All for 50CT, but I guess there is no harm in trying them on 60CT 😀

SETYMF might be of use here too. You are definitely needing to run a separate initialisation program to set up the mixer, by default most sources are muted.

Thanks all, I did try UNISOUND to no avail, figured I was just not using it properly but I guess it doesn't work for my Libretto anyway.

As for those utils, they do work 😀 the Libretto 60 is just a 50CT with a faster 100mhz Pentium released for JP market only. So far everything 50CT related has applied to this model 😁
I will try those drivers and report back.

I'm also going to look into this SETYMF, I assume it's either an ENV VAR or an application to load into autoexec.bat?

SETYMF is replacement to Yamaha's SETUPSA util that I made a while back for my own YMF71x based sound card, but it will work with most/any random YMF71x implementation and may prove useful here even if others fail. You can get it from a link in my signature.

BLASTER variable doesn't mean anything on its own, it only tells software what settings the card is configured to, but doesn't actually do any of the configuration, for that you need some initialisation util. Unisound doesn't seem to work, it doesn't seem you have tried SETUPSA ?

I tried out your SETYMF application but it doesn't like the chip on the Libretto... I had to use the /forcepnp (if I recall correctly) switch and even that only got me so far. None of the sound tests worked, producing no sound or errors.

I'm going to try SETUPSA as it was included in that ZIP file posted above...

I wanted to give an update so far...

My system does NOT have a CMOS battery (had to remove due to leakage) and I was noticing that my SBPro DMA setting was constantly reverting back to Channel 0 despite changing it to "Same as WSS". Even when I would leave the laptop plugged into AC, change the setting and reboot (no F1 error), still reverts...

Well now miraculously it seems to be defaulting to "Same as WSS", even when I remove the system battery for battery swap (I have multiple batteries for the laptop).

I tried running setupsa.exe and i got to see that all the sound levels checked out in the program (nothing of relevance was muted), so I exited and to my amazement, Doom2 produced sound!!

I will do some more testing, but I think it was that pesky BIOS setting constantly reverting even after I would change it.

WSS and SB Pro settings should not conflict. I used to have a similar Toshiba and I remember having to go through every permutation of those settings before finally finding one that worked. Make sure your BLASTER environment variable always matches what you selected in the BIOS.

This makes me think the laptop has OPL3-SA in it, aka YMF701, which is not PnP and is not compatible with YMF711/5/8/9 that SETYMF can deal with, which is why it wasn't working.
SETUPSA supports YMF701 and will update BLASTER variable in AUTOEXEC.BAT too. Any BIOS settings should be overridden and essentially not matter.

So the the final way to get it to work is to run SETUPSA, exit out of it, and THEN I can hear sounds in Doom2. Sadly if I want to boot into Windows again, this causes a resource conflict and thus I need to do a full reboot to get sound under Windows again.
