- * @short_description: Interface for elements that provide mixer operations

- *
- * Basic interface for hardware mixer controls.
- *
- * Applications rarely need to use this interface, it is provided mainly
- * for system-level mixer applets and the like. Volume control in playback
- * applications should be done using a <classname>volume</classname>
- * element or, if available, using the <quote>volume</quote> property of
- * the audio sink element used (as provided by <classname>pulsesink</classname>
- * for example), or even better: just use the <classname>playbin2</classname>
- * element's <quote>volume</quote> property.
- *
- * Usage: In order to use the <classname>GstMixer</classname> interface, the
- * element needs to be at least in READY state (so that the element has opened
- * the mixer device). Once the element has been set to READY state or higher,
- * it can be cast to a <classname>GstMixer</classname> using the GST_MIXER
- * macro (in C) and the mixer API can be used.
