    Hi,

    My version is Qt Creator 4.8.2 based on Qt 5.11.3(GCC 8.3.0,32 Bit)
    My operating system is Raspbian
    My device is Raspberry Pi Compute Module CM3
    I got my voice with low pass and high pass circuits that I installed in the pwm outputs of the card. I get sound when I play it with Omxplayer.

    @Mucahit You forgot to mention Qt version you're using (you will not find it in "About Qt Creator..." dialog).

      Hi,

      How can I learn Qt version ? I thought I would find About Qt Creator.

        About Qt Creator

        This only shows Qt version which was used to build QtCreator.
        What Qt version did you install?
        If you do not know then go to "Tools/Options.../Kits" and check the Kit you're using.

            @Mucahit Playing video with some other application (like VCL) does work properly on your RPi?

                @Mucahit Could be that you're missing some GStreamer plug-ins. Do you see any warnings/errors in terminal when running your app?

                    @Mucahit Does sound work if you play file with gst-play-1.0? If not, try installing gst-omx plugins.

                      Since it's Debian use "apt-get install". You can use "apt-get search gstreamer" to search for GStreamer packages.

                        AFAIK right command is apt-cache search, not apt-get search

                          @Konstantin-Tokarev According to the apt manpage on my Ubuntu 18.04 "apt search" can be used to search for available packages. "apt-cache search" is also valid.
