<![CDATA[PCM Player - QtMultimedia [Solved]]]>Hello,

I have some problems when using some classes from QtMultimedia. I implemented the example from the page "QAudioOutput":http://qt-project.org/doc/qt-4.8/qaudiooutput.html.

The debugger says :
undefined reference to _imp___ZN12QAudioFormatC1Ev' undefined reference to _imp___ZN12QAudioFormat13setSampleRateEi'
undefined reference to `_imp___ZN12QAudioFormat15setChannelCountEi'
and so on, for every methode of the class QAudioFormat.

Does someone have an idea why?

Did you add multimedia to QT in your pro file ?

Hope it helps
