QtMultimedia hangs without pulseaudio

When pulseaudio is initialised by QMultimedia framework and no pulseaudio is instaled it hangs.
F.e on that code:
QAudioDeviceInfo::availableDevices(QAudio::AudioOutput);

Unfortunately under all Debian/Ubuntu based distros the framework is tided to pulseaudio so when user uninstalls pulse, apps related to framework hang.
If code above could just return empty list of devices than wait infinitely for pulseaudio.
