Hi all,  
Made myself a nice reusable preloader to go with a swf/voiceover loading framework, then realied I’d need a little bar to show progress of MP3 file.

All fine.

Make that, then notice that it’s crackling a lot from streaming, so I turn off streaming. It would seem Sound.getBytesLoaded() returns undefined if it’s not streaming.

1. Isn’t that a really stupid thing? Streaming precludes need for preloaded generally.

2. Is there a simple way around it. Tried some addEventLister stuff but .PROGRESS didn’t seem to trigger (might by AS3, I get so confused…)

Also tried using Sound.load(URL) instead of loadSound(URL) but to no avail.

I can just use a throbber for now but it’s a shame.

Any help is muchly appreciated.

Martin
