Add "default" to your list of keys available - to override the default audio device to be provided by your plugin. - - \code - { "Keys": [ "default" ] } - \endcode - - Unit tests are available to help in debugging new plugins. - - \sa QAbstractAudioDeviceInfo, QAbstractAudioOutput, QAbstractAudioInput - - Qt comes with plugins for Windows (WinMM and WASAPI), Linux (ALSA and PulseAudio), \macos / iOS - (CoreAudio), Android (OpenSL ES) and QNX. - - If 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, make sure the dependencies for the Qt plugins are - installed on the system and reconfigure Qt (e.g. alsa-devel package on Linux), 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) -*/ - -/*! - \fn QAudioSystemPlugin::QAudioSystemPlugin(QObject* parent) - - Constructs a new audio plugin with \a parent. - This is invoked automatically by the Q_PLUGIN_METADATA() macro. -*/ - -QAudioSystemPlugin::QAudioSystemPlugin(QObject* parent) : - QObject(parent) -{} - -/*! - \fn QAudioSystemPlugin::~QAudioSystemPlugin() - - Destroys the audio plugin. - You never have to call this explicitly.
