Need help with mp3 Firefox playbacks

[yul...@yahoo.com]

I am trying to load mp3 audios on Firefox. When I use the MIME_TYPE_AUDIO_MPEG_MP3, it was not working. And I saw the following post -

https://code.google.com/p/gwt-voices/issues/detail?id=30

I am using gwt-voices version 3..2.0

So I use the MIME_TYPE_AUDIO_BASIC and LOAD_STATE_SUPPORTED_MAYBE_READY

But I saw in the documentation that using this load state, the PlaybackCompleteEvent doesn't get call. 

Is there anyway to work around this issue? I needed the PlaybackCompleteEvent to get trigger. If there is some other status I can check manually, periodically it is okay as well.
