SYMPTOMS
========

When you install DirectX or one of the programs listed at the beginning of this
article (these programs all install DirectX), sounds may no longer be played on
your computer.

CAUSE
=====

This issue can occur if the DirectX Setup program installs a newer version of
the Sound Blaster audio drivers when you are using a Cyrix MediaGX processor.
The MediaGX processor emulates a Creative Labs Sound Blaster audio adapter.
However, the Sound Blaster drivers included with DirectX do not work with the
MediaGX processor.

To verify that your computer contains a MediaGX processor, follow these steps:

1. Click Start, point to Settings, and then click Control Panel.

2. Double-click System. If MediaGX is listed under Computer on the General tab,
  the processor is a MediaGX.

RESOLUTION
==========

To restore sound in Windows, follow these steps:

1. Click Start, point to Settings, and then click Control Panel.

2. Double-click System.

3. Click the Device Manager tab.

4. Double-click the Sound, Video And Game Controllers branch to expand it.

5. Click the Sound Blaster device, and then click Remove. If there is more than
  one Sound Blaster device, repeat this step to remove each Sound Blaster
  device.

6. If a game port device is listed, click the game port device, and then click
  Remove.

7. Click OK, close Control Panel, and then restart your computer.

8. When Windows starts, it detects the MediaGX processor and installs the
  correct audio drivers. If Windows does not detect the MediaGX processor,
  install the audio drivers provided by Cyrix or your computer manufacturer.

  For information about installing an audio driver, please see the following
  article in the Microsoft Knowledge Base:

MORE INFORMATION
================

To enable sound in programs that use DirectSound (this includes the programs
listed at the top of this article), contact your computer manufacturer or Cyrix
to obtain the Cyrix MediaGX DirectX 5.0 patch. This patch resolves a conflict
with DirectX 5.0 or 5.2 and the MediaGX processor.
