SYMPTOMS
On computers running Windows 98 Second Edition, sounds may intermittently be unable to play after Windows starts. (For example, .wav files may not play.) This problem may occur if both of the following conditions are true:
 * The program being used to play the sound uses the PlaySound application programming interface (API).
 * The computer has one or more Universal Serial Bus (USB) Human Interface Device (HID) devices installed, (for example, a USB speaker device).

After this occurs, further attempts to use the PlaySound API to play sounds do not work until you restart Windows.

NOTE: The Windows Startup sound may play successfully.



CAUSE
This issue can occur if a reference counter is not cleared properly by the Winmm.dll file while the the PlaySound API is being processed. If the reference counter is not cleared, the PlaySound API calls do not properly initialize and the sounds to not play.
