No Audio with Crystal Audio or SoundBlaster AWE32

• Microsoft Windows NT Workstation version 4.0
• Microsoft Windows NT Server version 4.0

SYMPTOMS

You do not receive audio from your Crystal Semiconductor audio chip or Creative Labs SoundBlaster AWE32 PnP Wavetable Synthesizer.

CAUSE

This problem may occur for either of the following reasons:

• You ran PnPISA from the Windows NT 4.0 CD (or any of the Service Packs) and selected "Do not install a driver (Windows NT will not prompt you again)."
• The Creative Labs Advanced Wavetable Effects (AWE) Synthesizer is installed and a Windows NT driver was not available when you were prompted to use the Windows NT default driver. In this scenario, Do Not Install Driver was chosen automatically.

RESOLUTION

You can resolve this problem by obtaining the Windows NT 4.0 Service Pack 3 CD-ROM or by downloading Service Pack 3. For information on obtaining the latest Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

Service Pack 3 - CD-ROM Version

Using the Windows NT 4.0 Service Pack 3 CD-ROM, perform the following steps to correct this problem:

1. Start a command prompt.

2. Go to the folder on the Service Pack 3 CD-ROM for your architecture (for example, i386 for Intel.)

3. Type the following command:

         devpre devupd.inf
   

   NOTE: Devpre does not support UNC paths. You must map a network drive if you are attaching to the Service Pack 3 CD-ROM across a network.

4. A dialog box titled Windows NT Setup reads "Setup is examining your computer's hardware."

5. You may receive a prompt for the path of your audio drivers.

   a. Enter the path name to the Service Pack 3 CD-ROM for the Audio

         driver.
   

   b. Click OK on the Select Device screen.

   c. If you are not presented with resource settings, click Set

         Configuration Manually.
   

   d. If there are conflicting devices at the bottom of the screen, resolve

         them first by selecting a basic configuration that allows the
         selection of resources that do not conflict with devices already
         installed.
   

         To change resources, highlight the offending setting in the Resource
         Settings window, click Change Setting and select a setting that does
         not conflict with another device, and then click OK. Repeat for any
         settings that show a conflict.
   

6. If you receive a prompt for any other functions, follow the previous steps.

7. Restart your computer.

8. Your audio card should be working properly at this point. If you need to change the resources that your card is using, open the Multimedia utility in Control Panel, click the Devices tab, click Properties for the Crystal Semiconductor driver or the Creative Labs SoundBlaster Plug and Play driver, and then click Settings. This opens the same resource dialog box that was invoked when installing the device.

Service Pack 3 - Download Version

Because the downloadable version of the Service Pack is in CAB format, you must manually extract the files with the /x switch before running DEVPRE. Please see the Readme.txt file included with the self-extracting version of Service Pack 3 for more information.

1. Start a command prompt.

2. Create a temporary folder on your hard disk, copy the Service Pack executable to this folder, and extract the files contained in the Service Pack by typing the name of the executable followed by the /x switch:

         <Filename> /x
   

3. Type the following command:

         devpre devupd.inf
   

   NOTE: Devpre does not support UNC paths. You must map a network drive if you are attaching to the Service Pack 3 CD-ROM across a network.

4. A dialog box titled Windows NT Setup reads "Setup is examining your computer's hardware."

5. You may receive a prompt for the path of your audio drivers.

   a. Enter the path name to the Service Pack 3 CD-ROM for the Audio

         driver.
   

   b. Click OK on the Select Device screen.

   c. If you are not presented with resource settings, click Set

         Configuration Manually.
   

   d. If there are conflicting devices at the bottom of the screen, resolve

         them first by selecting a basic configuration that allows the

         Settings window, click Change Setting and select a setting that does
         not conflict with another device, and then click OK. Repeat for any
