Selecting Audio Driver in Control Panel Causes Error

• Microsoft Windows NT operating system version 3.1
• Microsoft Windows NT Advanced Server version 3.1

SYMPTOMS

When you install or select a multimedia sound card driver in Control Panel, the following DR WATSON error message may appear:

   An application error has occurred and an application error log is being
   generated.

      CONTROL.EXE

   Exception: Illegal Instruction (xxxxxxxx) Address (xxxxxxxx)

CAUSE

This error message appears when MIPS or Alpha versions of the drivers have been installed instead of the Intel (I386) versions.

RESOLUTION

To avoid this problem, replace the existing drivers with the correct versions, expanded from disk or CD-ROM.

To determine which driver files are installed when a specific sound card is selected, look at the [installable.drivers] and the individual driver sections in the MMDRIVER.INF file. This file is in the SYSTEM32 subdirectory. The drivers are usually placed in the SYSTEM32 or SYSTEM32\DRIVERS directories, or both.

You can then choose to delete the files and remove the sound card reference from the Drivers utility of Control Panel, and then reinstall the drivers. Otherwise, you can manually expand all the driver files for that card from disk or CD-ROM using the EXPAND.EXE utility.
