This is automatic by default - and will only be compiled into the library if the dependencies are installed. - eg. alsa-devel package installed for linux. - - If the builtin backend is not compiled into the QtMultimedia library and - no audio plugins are available a fallback dummy backend will be used. - This should print out warnings if this is the case when you try and use QAudioInput or QAudioOutput. To fix this problem - reconfigure Qt using -audio-backend or create your own plugin with a default - key to always override the dummy fallback. The easiest way to determine - if you have only a dummy backend is to get a list of available audio devices. - - QAudioDeviceInfo::availableDevices(QAudio::AudioOutput).size() = 0 (dummy backend) -*/ - -/*! - Construct a new audio plugin with \a parent. - This is invoked automatically by the Q_EXPORT_PLUGIN2() macro. -*/ - -QAudioSystemPlugin::QAudioSystemPlugin(QObject* parent) : - QObject(parent) -{} - -/*! - Destroy the audio plugin - - You never have to call this explicitly.
