I'm not able to reproduce this on Chrome Stable 15.0.874.106 (Official Build 
107270) on OSX

Can you include the file you're trying to play?

Is there any solution for this. I am also facing the same issue
<Code>
SoundController soundController = new SoundController();
sound = 
SoundController.createSound(Sound.MIME_TYPE_AUDIO_MPEG,GWT.getHostPageBaseURL()+
"DataSourceServlet?FilePath=C:/Users/Rubini/Desktop/songs/7 Am Arivu/7 Am 
Arivu/Yamma Yamma - TamilWire.com.mp3");
                                //soundController.setPreferredSoundType(WebAudioSound.class);
                //soundController.setPreferredSoundType(Html5Sound.class);
                //soundController.setPreferredSoundType(NativeSound.class);
                //soundController.setPreferredSoundType(FlashSound.class);
 sound.play();
</Code>

There are some Web Audio API fixes in the 2.1.5 release which will hopefully 
resolve this issue. I'd be interested in hearing your findings.

In particular 2.1.5 fixes two Web Audio API (which affects Chrome) issues:

1. immediately calling `sound.play()` after creating the sound `Sound sound = 
soundController.createSound()` would throw an exception

2. If the sound file URL was invalid or the retrieval of the audio file failed, 
the calling `sound.play()` would throw an exception
