PRB: Unable to Play .Wav File from Applet or AudioClip

 Last reviewed: January 29, 1998
Article ID: Q178707
The information in this article applies to:
  • Microsoft Visual J++, versions 1.0, 1.1
  • SDK for Java, versions 1.51, 2.0, 2.01

SYMPTOMS

When an Applet tries to play a .wav file from an applet using the Applet.play() method or the AudioClip.play() method, either nothing happens or you get the following console output: 

   NativeAudioStream: invalid file type

CAUSE

The JDK 1.02 and JDK 1.1x APIs are able to play only AU files. The AU files need to be 8 bit, ulaw, 8000 Hz, and one channel.

RESOLUTION

Use a product that is capable of creating AU files according to these specifications. Convert the .wav file and change the URL to point to the AU file.

STATUS

This behavior is by design.
