bug while changing volume on play

[GoogleCodeExporter]

Reproducing the problem:
1. start to play voice file.
2. change music volume.

I am expecting to hear volume changing real-time.
Instead of that, I need to stop playing file, the next, change volume and start 
playing again.

<code>
SoundController soundController = new SoundController();
Sound sound = soundController.createSound(Sound.MIME_TYPE_AUDIO_MPEG,
        "url/to/your/sound/file.mp3");
sound.setVolume(20);
sound.play(); //File has being loaded from server and is playing some music. 

//After some time I am changing volume.
sound.setVolume(100); //In that place volume are not going to change. It has 
the same value(20). If I press stop and play it will be 100.
</code>

I was not precise while writing "press stop and play". Of course, I am saying 
about calling gwt-voices methods.

This appears to depend on the implementation used. For example, Html5Sound 
updates on the fly:

    audio.getAudioElement().setVolume(volume / 100d);

as does FlashSound:

      voicesMovie.setVolume(soundNumber, volume);

and NativeSound:

    elem.setAttribute("volume", "" + volume);

However, WebAudioSound's setVolume() only modifies the internal state variable 
without updating the currently playing sound's gain node.

I am not sure if the API makes any guarantees as to behaviour, but it's 
troublesome that the different implementations are so different.

Just noticed this issue myself.
Is the recommendation these days just to use Html5 audio on everything?
