messages:

  No wave device that can play files in the current format is installed. Use
  the Drivers option to install the wave device.

  Multimedia device Sound failed.

NOTE: This article does not apply to Microsoft Windows 95. If you are using
Windows 95, please see the following article in the Microsoft Knowledge Base:

  Q133365 Windows 95: Troubleshooting Problems with Compressed Audio

NOTE: This article applies to those applications that use MSACM version 2.0 only.
For information about applications that use MSACM version 1.0, please see the
following article in the Microsoft Knowledge Base:

  Q100546 MSACM 1.0: Compressed Audio Will Not Play

RESOLUTION
==========

These symptoms can occur if the Microsoft Audio Compression Manager (MSACM) is
not correctly installed. MSACM is used for playing compressed Sound (.wav) files
.

To verify that MSACM is installed correctly, do the following:

NOTE: The following steps involve searching for, copying, and modifying files and
folders. For more information about how to accomplish these tasks, see your
Windows printed documentation or online help.

1. From MS-DOS, copy the following files from the appropriate folder on the
  compact disc to the Windows System folder on the hard drive:

  Acmcmprs.dll
  Imaadpcm.acm (used only by some programs)
  Msgsm610.acm (used only by some programs)
  Msacm.dll
  Msacm.drv
  Msadpcm.acm

  If you are prompted, replace any currently installed versions of those files.
  This also verifies that only compatible versions of MSACM files are
  installed.

  NOTE: Check your Windows folder and Windows System folder to ensure that there
  are not multiple copies of the MSACM files.

  NOTE: In Encarta 1995, it is not possible to manually copy these files from
  the compact disc. If the MSACM files are corrupt, you must rename or delete
  them from your hard drive, then remove Encarta 1995 by running the Setup
  program. After removing, run Setup again to reinstall Encarta. Setup then
  installs the MSACM files.

2. Use a text editor, such as Microsoft Notepad, to create or modify the
  following lines in the System.ini file, which is located in the Windows
  folder:

  [Drivers]
  WaveMapper=MSACM.DRV
  MSACM.msadpcm=MSADPCM.ACM
  MSACM.imaadpcm=IMAADPCM.ACM
  MSACM.msgsm610=MSGSM610.ACM

  NOTE: Only certain drivers are needed to play certain types of compressed
  audio.

3. Verify that the Msacm.ini file has the correct settings. This file is located
  in the Windows folder. Below is an example of the Msacm.ini:

  [Priority]
  Priority1=1, MS-PCM, Microsoft PCM Converter
  Priority2=1, MS-ADPCM, Microsoft ADPCM CODEC
  Priority3=1, Microsoft IMA ADPCM, Microsoft IMA ADPCM Codec
  Priority4=1, Microsoft GSM 6.10, Microsoft GSM 6.10 Audio CODEC

  A driver with a priority set to 0 won't play sound or causes the "No wave
  device that can play files in the current format...." error message to be
  displayed. To correct the problem, set each line to = 1.

Pronunciations and Foreign Language Sounds
------------------------------------------

Some programs use the GSM 6.10 CODEC driver for playing pronunciations or foreign
language samples. If normal sounds play correctly, but pronunciations fail,
follow the steps above to verify correct installation of MSACM. If the steps
above do not correct the problem, please see the following article in the
Microsoft Knowledge Base:

  Q112554 No Pronunciations or Foreign Language Sounds

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

If MSACM is not installed properly, simply reinstalling a program that uses it
does not fix the problem. If the Setup application for the Microsoft program
finds MSACM files present on the system, it determines that MSACM is already
installed, and does not reinstall MSACM.
