    Hello!

    I'm developing control app on Raspberry Pi.

    I wanted to apply sound alarms, when specific events occured telling for example about signal disapear,, and QSound is looking like something I need, but I still get error: " cannot find -lQtMultimedia" after added "QT+= multimedia" to pro file.

    I noticed that in "/usr/include/qt4" I don't have required librarry.

    Doesn't help:
    apt-get install qtmultimedia5-dev
    apt-get install qml-module-qtmultimedia
    apt install libqt5multimedia5

    I think what I need is libqt4-multimedia, but it looks like it was removed...
    apt searching giving me all libs I need for example libqt4-network or libqt4-svg
    but I can't find libqt4-multimedia.

    QMake version 3.1
    I have both: Qt version 5.11.3 and 4.8 but this is little older project written in 4.8.

    Please help me to make QSound working or maybe is a another way to make sound alarms?

      If you're using Qt 5 then no, you don't need it as it is for Qt 4.
      So: which Qt version do you actually use? Qt 5 or Qt 4?

          @Pauaqq Which Qt 4 packages did you install?

          You should also consider to use Qt 5 instead of Qt 4 as Qt 4 reached end of life long time ago.

            I installed "libqt4-dev" and these was automatic installed:

            libqt4-dbus, libqt4-declarative, libqt4-designer, libqt4-dev-bin, libqt4-help,
            libqt4-network, libqt4-opengl, libqt4-opengl-dev, libqt4-qt3support, libqt4-script,
            libqt4-scripttools, libqt4-sql, libqt4-sql-mysql, libqt4-sql-sqlite, libqt4-svg,
            libqt4-test, libqt4-xml, libqt4-xmlpatterns

            Yeah, I know. This is little older project I need to add some features to it asap.

              Hi,

              You may have to use the Qt 4 phonon module.
