Problem: audio recorder gets error at setup time:

Dec 22 23:59:51.159 
com.nielsmayer.voicetogoog.testDev_voicetogoog4895b46d.13492410              
default   9000  defaultServiceProvider::requestService(): no service found for 
- "com.nokia.qt.audiosource" 

[00:27] <npm> how does one go about recording audio with QMediaRecorder() (like 
http://www.qt.gitorious.org/qt-mobility/qt-mobility/blobs/master/examples/audior
ecorder/audiorecorder.cpp )
[00:27] <npm> I get errors like
[00:27] <npm> com.nielsmayer.voicetogoog.testDev_voicetogoog4895b46d.13492410   
           default   9000  defaultServiceProvider::requestService(): no service 
found for - "com.nokia.qt.audiosource"
[00:39] <npm> Q_MEDIASERVICE_AUDIOSOURCE is set to "com.nokia.qt.audiosource" 
in 
http://www.qt.gitorious.org/qt-mobility/qt-mobility/blobs/f7071081b7a83e42033df5
7d17593c3fd3e70608/src/multimedia/qmediaserviceprovider.h
[00:39] <npm> ...

so how to setup /usr/lib/qt4/plugins/mediaservice/libqtmedia_blackberry.so

[01:06] <npm> in other words the service plugin points to nonexistant 
com.nokia.qt.audiosource when there seems to be a blackberry mediaservice 
plugin that isn't being invoked

 Server is going away. 

And, yes, by "Server is going away" the embedded webserver part of the app 
works, just has no data to display :-(

After removing code similar to 
http://www.qt.gitorious.org/qt-mobility/qt-mobility/blobs/master/examples/audior
ecorder/audiorecorder.cpp which uses QMediaRecorder from the BB10 build, indeed 
the `no service found for - "com.nokia.qt.audiosource"' message goes away. TBD, 
whether the QML Audio playback part works or not. Will install data&database 
from N9 to see whether other parts are working, and/or recode segments emitting

 calling Recorder.beginRecording()...scripts/audio.js:37: ReferenceError: Can't find variable: Recorder

by implementing the elided 'Recorder' object in QML using bb.multimedia?

A somewhat official answer to the status of this issue on BB10 and hope for 
eventual support?

http://devblog.blackberry.com/2012/11/writing-qt-apps-blackberry-10/

"The QtMultimediaKit module is included in the BlackBerry 10 NDK except for 
QMediaRecorderControl (and so no QMediaRecorder) and Camera APIs. Development 
teams in RIM are working to provide support for these and other modules in the 
future."
