--------------------------------------------------------------
DESCRIPTION

The audio plug-in card with the CS-4231 chipset and the Aztec ASIC is 
improperly detected as a standard CS-4231 audio chipset, which is the 
chipset in the IBM PC750. As a result, the audio driver loaded does not 
actually support the audio card.

One symptom of this occurs running the MACAW.AVI file shipped with OS/2 
Warp 4. The movie plays, but any attempt to close it will cause the 
system to lock up.

RESOLUTION

The sniffer program generically detects the CS-4231 audio chipset in 
order to support the IBM PC750. 

To the resolve the problem: 

1. Open the OS/2 System folder.

2. Double click on System Setup.

3. Open the Install/Remove folder.

4. Double click on Selective Install.

5. Select Multimedia Device Support.

6. Select Remove, to remove Crystal Audio CS-4231 from
   the Devices in System to be installed window.

7. Select the correct Supported Device type for your
   audio adapter, then select OK.
