-    Qt supports win32, linux(alsa) and OS X standard (builtin to the
-    QtMultimedia library at compile time).
+    Qt comes with plugins for Windows (WinMM and WASAPI), Linux (ALSA and PulseAudio), OS X / iOS
+    (CoreAudio), Android (OpenSL ES) and QNX.
 
-    You can support other backends other than these predefined ones by
-    creating a plugin subclassing QAudioSystemPlugin, QAbstractAudioDeviceInfo,
-    QAbstractAudioOutput and QAbstractAudioInput.
-
-
-    The builtin backend 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.
+    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 reconfigure Qt with the required
-    dependencies (e.g. alsa-devel package) available 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.
