This is taken from the Warp Information file (Multimedia):
To add Windows** support for the Crystal Semiconductor** audio devices
on the ThinkPad* 750 or 755, you need to:
1. Edit the SYSTEM.INI file, which is located in the directory you
load Windows from, usually the \WINDOWS directory.
2. Copy the Crystal Semiconductor CS4231 drivers from the \OS2
directory to the appropriate Windows directories.
First, edit the SYSTEM.INI file:
1. Add the following lines under the heading [drivers].
Wave=CS31BA11.DRV
Aux=CS31BA11.DRV
Mixer=CS31BA11.DRV
2. Add the following line under the heading [386enh].
Device=vsndsys.386
3. Add the contents of the TP750INI.ADD file to the end of the
SYSTEM.INI file. You can use your editor to perform this
operation, or you can use the COPY command.
To use the COPY command, enter the following at the command
prompt:
COPY d:\WINDOWS\SYSTEM.INI+o:\OS2\DRIVERS\CS4231\TP750INI.ADD
where o: is the drive that OS/2 is installed on and d: is the
drive that Windows is installed on.
Second, copy the Crystal Semiconductor CS4231 drivers from the \OS2
directory to the Windows directories:
1. Copy the file CS31BA11.INI from \OS2\DRIVERS\CS4231 to your
\WINDOWS directory.
2. Copy the file CS31BA11.DRV from \OS2\DRIVERS\CS4231 to your
\WINDOWS\SYSTEM directory.
3. Copy the file VSNDSYS.386 from \OS2\DRIVERS\CS4231 to your
\WINDOWS\SYSTEM directory.

Subject: Sound under Win-OS/2

Was there some sort of special procedure to get multimedia sound
working under Win-OS/2 on a TP750 (the one with the Crystal Semi
sound chipset)? I could've sworn I'd gotten it working before,
but I've reinstalled Win-OS/2 and MMOS/2 several times without
any luck. The Win-OS/2 system sounds are greyed out, and every
time I try to start a multimedia app, it complains that there
are no drivers installed. I go to install drivers in the control
panel and there are no crystal semi drivers.
This is a late gamma of Warp with Win-OS/2, the one that came with
DevCon. If someone else knows what's up, great. Or if you have
the release version of Warp with Win-OS/2 and don't have any
problems, tell me and I'll see if I can get an updated version.
