The information in this article applies to:

Microsoft Windows 95

SYMPTOMS

After you install the drivers for the Diamond Sonic Sound LX sound card, the following problems occur:

When you restart the computer you receive an error message stating that the Mmsystem.dll file was changed.
No sound events occur and the Play button is unavailable in the Sounds tool in Control Panel.
You do not see a speaker icon on the taskbar.

It may seem as if the drivers for the Diamond Sonic Sound LX sound card are not functioning.

CAUSE

The Setup program for the Diamond Sonic Sound LX sound card (and other Diamond sound cards) makes the following changes to the [drivers] section of the System.ini file:

WAVE=SND16.DRV
MIDI=SND16.DRV

The Setup program also replaces the Mmsystem.dll file.

RESOLUTION

Use any text editor (such as Notepad) to edit the System.ini file. Change the line that reads

   WAVE=SND16.DRV

to read:

   WAVE=MMSYSTEM.DLL.

Change the line that read

   MIDI=SND16.DRV

to read:

   MIDI=MMSYSTEM.DLL

After you make these changes, save and then close the file.

Also, extract the original Mmsystem.dll file to the Windows\System folder. To do so, follow these steps:

Restart your computer. When you see the "Starting Windows 95" message, press the F8 key, then choose Safe Mode Command Prompt Only from the Startup menu.
NOTE: If you are using a Windows 95 CD-ROM, choose Step-by-Step Confirmation and choose Yes only for the CD-ROM drivers.
If you are using Windows 95 disks, type the following line at the MS-DOS prompt
```
     extract <drive>:\win95_08.cab mmsystem.dll /l c:\windows\system
```
where <drive> is the drive letter of the floppy disk drive you are using. Make sure to insert Disk 8 in the floppy disk drive.
If you are using a Windows 95 CD-ROM, type the following line at the MS-DOS prompt
```
     extract <drive>:\win95\win95_08.cab mmsystem.dll /l c:\windows\system
```
where <drive> is the drive letter of the CD-ROM drive.
After you extract the Mmsystem.dll file, restart your computer normally.
