    QAudioOutput doesnt produce any sound on n950 PR1.2 beta

    Hi

    I'm trying to play RAW audio file 44100Hz, stereo, 16 bit
    no error messages but still, no sound
    and the QAudioOutput stays in ActiveState

    what is wrong there? if its even possible to get sound with QAudioOutput on Harmattan?

    Thanks

    Can you play the file using GStreamer directly? Can you share the file?

    You can use the below tools -

    * gst-launch - Which is a easy testing and prototyping command line tool
    * gst-inspect - Which provides the list of elements provided by the plugins installed in the system.

    They are not availble by default -
    Check this for help in installing on N9.

    you would want to use your own pipeline.
    You can check on google for some usage examples.

    From command line: gst-launch playbin2 uri="file:///home/user/myfile.something"
    In our wiki you can find several examples which show how to use it with Qt.

    Did you check the volume level of the phone?
