Garbled Sounds in Windows Sound System Using IMAADPCM.ACM (128759)


The information in this article applies to:

  • Microsoft Windows Sound System 2.0
This article was previously published under Q128759

SYMPTOMS

When you are playing a .WAV file created with the IMAADPCM.ACM compression manager included with Windows Sound System version 2.0a, you may hear static or garbled sound.

CAUSE

This behavior can occur if you are using a different version of the IMAADPCM.ACM file to play the .WAV file than the one that was in use when the .WAV file was created.

RESOLUTION

To correct this behavior, replace the IMAADPCM.ACM file with the one included with Windows Sound System 2.0a. The correct file has the following size and date:

IMAADPCM.ACM 10,320 12-15-93 2:00a

MORE INFORMATION

A later version of the IMAADPCM.ACM file is installed when you install Microsoft Video for Windows Run-Time Edition version 1.1e. Note also that .WAV files created using the newer version of the file may not play correctly using the older version.
