Thanks for catching this one.

Ony one nit: the test qtmultimedia-opensource-src-5.8.0/config.tests/pulseaudio/pulseaudio.cpp
checks for:

  #include <pulse/pulseaudio.h>
  #include <pulse/glib-mainloop.h>

and pulse/glib-mainloop.h is only installed by the pulseaudio package in case
BR2_PACKAGE_LIBGLIB2 is selected. The Dependency should therefore be (not sure
about the libglib2 one):

 +ifeq ($(BR2_PACKAGE_LIBGLIB2)$(BR2_PACKAGE_PULSEAUDIO),yy)
 +QT5MULTIMEDIA_DEPENDENCIES += libglib2 pulseaudio
 +endif

By the way, the dependency on alsa is missing too...

Regards,
Peter
