Microphone starting muted on AIR application SDK 2.5

Question

According to the documentation
http://help.adobe.com/en_US/air/reference/html/flash/media/Microphone.html
"Content running in the AIR application sandbox does not need permission to access the microphone and no dialog is displayed. AIR content running outside the application sandbox does require permission and the Privacy dialog is displayed"
But I'm having problems starting the Microphone object, which starts muted and permissions need to be given right clicking on the flash object.
This function returns always true before permissions is given:
public function isMuted():Boolean {
var mic:Microphone = Microphone.getMicrophone();
return mic.muted;
The swf loaded is inside the application sandbox, but it's failing also from the debugger.
Any ideas what else to look?
Thanks,
Guille

Updated note:
This might be a possible work around...
The limitations I mentioned in my previous email apply when including the SWF file ‘for rendering’ – i.e. when using an <object/> tag.
In AIR a developer can include a SWF file as a script – i.e. using a script tag like so: <script src="lib/applicationupdater_ui.swf" type="application/x-shockwave-flash"></script>. When doing this, the SWF is loaded in the application sandbox and JavaScript can call AS functions as if they were JS functions.
If the customer’s code doesn’t depend on displaying things (or the UI part is reasonably well separated from the rest of the logic), it should work without any changes. If not, it might require some changes, but still not as radical as rewriting their code to JavaScript.  A simple example of using a SWF in this way can be found at http://www.stratulat.com/blog/update-your-javascript-air-application-with-ease - it shows how to use the Application Updater library (a SWF) in a JavaScript application. This could be a starting point for the customer about how to use a SWF as a script and how it should “look like” in order to be used this way (as the framework is open-source).
