Probably some more knowledgeable people can give you a better answer but according to this
https://www.os2world.com/wiki/index.php/Sound … _OS2_S.B._TOOLS
and this
https://www.bttr-software.de/forum/board_entry.php?id=16258
, though both refer to later versions of os2

You'll need to also have a driver loaded in config.sys
No idea which driver you'll need for the oak card, though I guess the standard soundblaster one might work.

Hi, not sure if I can help. 🙁

While I did use OS/2 Warp 3 with a sound card before, it was an Media Vision Pro AudioSpectrum 16.
- And that card was directly supported by MMPM/2 add-on of OS/2 2.1x (now part of Warp).

http://www.amoretro.de/2012/09/media-vision-p … soundkarte.html

It also had two soundcards in one - the PAS16 itself and the Thunderboard (Sound Blaster 1.5).

So it was possible to use the 16-Bit 44 KHz Stereo PAS16 side on OS/2 for OS/2 native applications (multimedia; video, music),
while the "legacy" part (Thunderboard) was available to DOS applications/games and Win-OS/2.
- Even more, Windows 3.1 (and thus, Win-OS/2) also had a Thunderboard driver shipped as part of the default installation.
(Edit: Just noticed there's a Win-OS/2 driver, tbos2.zip. Maybe useful for PAS16 owners reading this.)

Both parts could also work same time, of course.
So a DOS game and and an OS/2 music player (say PowerMOD) could be running same time.
Recording worked independently, too.

Only down-side was simultaneous OPL3 use.
I think there was an optional patch released that allowed Win-OS/2 to use OPL3..

Edit: It's "pas16opl3.zip" - not sure if it's generic, though.
Because the PAS16 had it's control port at port 388/389h (same as AdLib's port)..

For OAK OTI601 Mozart Chip, I found these drivers so far (just a quick search):
https://www.philscomputerlab.com/btc-1820-moz … oak-oti601.html

These archives contain OS/2 drivers:
btc_1820w_drivers.zip
btc_1820u_drivers.zip
btc_1820t_drivers.zip
btc_1820_drivers.zip

Good luck! 😀

And please don't despair if it needs a bit of fiddling.
OS/2 was (is) really nice - once it's configured correctly.

PS: In case the Mozart drivers provide no solution, this might be helpful for Win-OS/2 audio sharing:

That seems to be a good direction to follow.

though this makes it a bit more awkward

2         Licence, Registering

4
5         Developing this driver has taken a considerable amount of time. I'm
6         sure you'll honor my work, so there are no restrictions in the
7         shareware version!
8         If you register, you will be able to turn off the cuckoo.
9
10         You may try this program for 30 days. If you  want to continue to use
11         it, you must register. If you don't like the driver, simply DEL it.
12
13         !! Warning: If you are using shareware without registering, you'll
14         !! certainly descend into Hell some day. Even if you don't bother,
15         !! please register.
16
17         Please use the registration form supplied.
18
19         Optionally, you can order a disk with the driver.

In OS/2 and Win-OS/2 sound is playing fine (digital audio & midi), but DOS wont play sound.

I have configured both config.sys and autoexec.bat

Autoexec.bat

SET SOUND=C:\MOZART
SET BLASTER=A220 I5 D1 T4

config.sys

DEVICE=C:\MMOS2\MZTDD.SYS /N:MOZART1$ /D0 /I11 /B530 /S1,220,1,5
DEVICE=C:\MMOS2\MZTVDD.SYS MOZART1$

I will keep trying my luck

Thats driver i used.

Hi, did you playing with the DOS settings of OS/2 already?
Or does AdLib (FM/OPL2) work in any DOS games?
Trying to get FM working might be the simplest, because it's just port writes to port 388/389h (AdLib port).

Hi,

yes, i played in OS/2 DOS DOOM2 (doom2.exe -nosound) without sound and some settings for dos session

DOS_BACKGROUND_EXECUTION OFF
DOS_BREAK OFF
DOS_FCBS 16
DOS_FCBS_KEEP 8
DOS_FILES 20
DOS_HIGH OFF
DOS_RMSIZE 640
DOS_UMB OFF

DPMI_DOS_API AUTO
DPMI_MEMORY_LIMIT 8
DPMI_NETWORK_BUFF_SIZE 8

EMS_FRAME_LOCATION AUTO
EMS_HIGH_OS_REGION 0
EMS_LOW_OS_REGION 384
EMS_MEMORY_LIMIT 2048

HW_NOSOUND OFF
HW_ROM_TO_RAM ON
HW_TIMER ON

IDLE_SECONDS 0
IDLE_SENSITIVITY 100

INT_DURING_IO ON

VIDEO_TRETRACE_EMULATION OFF
VIDEO_ROM_EMULATION ON
VIDEO_SWITCH_NOTIFICATION OFF

XMS_HANDLES 32
XMS_MEMORY_LIMIT 2048
XMS_MINIMUM_HMA 0

My System is dual-boot (MS-DOS 6.22 & OS/2 Warp3). Under MS-DOS i played various games (doom, warcraft, hexen, dark forces, ...) and FM and OPL3 is working.

Hi, you can try setting IOPL=YES in config.sys, to allow direct hardware access.

Also important is VME=YES, which enhances stability.
VME is an enhanced form of V86 and supported from late 486 CPUs onwards.
All Pentiums have it. OS/2 supports it since Warp 3.

https://www.teamos2hamburg.de/projects/csdp/15_additional

Hi,

added IOPL=YES to config.sys. Now music works (adlib compatible) in games 😀 One step further.

But FM wont work

Later i will try the other option VME=YES

Hi, I'm glad it works a little bit now!

I'll have some OS/2 VMs here, so I can try to get sound working and then write back.

Needs a bit of time, though and I can't make any promisses. 🙁

Btw, here's some Information about OS/2 and VME.
The VME stuff is quite technical, though.
Anyway, might be interesting to know how important the Pentium was at the time.
Memory managers like QEMM 7.5 and up had VME support, too.
Late 486 processors had it, too.

glad you pointed that out. I managed to get my PAS16 to work yesterday in my P60 (PCD-5H).
next I will install OS2 2.0 and then install MM/OS2 with PAS16 support. OS 2.1 does not install due to HardDisk issues (too large).

You're welcome. I'm also glad to hear you're giving 2.0 a try. ^^
A friend of our family used to work at Siemens at had used OS/2 2.0 a lot.

What makes OS/2 2.0 so special is it's use of Windows 3.0 for Win-OS/2,
which I think can also run the Real-Mode kernal on OS/2.

It also had the original 16-Bit graphics drivers used, I think.
I vaguely remember there was a free update to OS/2 2.0 users that contained new, fast 32-Bit graphics drivers.

Edit: I did a bit of testing. Commander Keen 4 did run okay so far, with music/sfx (full screen).
Frederik Pohl's Gateway did hang the whole VM for some reason.
I'll try to run a shareware version of Doom this night.
