I am trying to do an application where the audio input (microphone) and the audio output work at the same time in QT using QAudioInput and QAudioOutput. The AudioInput and the AudioOutput examples from Qt work good on the imx6. But when I try to write an application where both are active (Audio input and output) my application does not work under imx6. I tried my application under Linux and it works fine, only when it comes to imx6 it doesnt work. What elso do I need to configure so that the audio mixer works correctly?
