* SECTION:element-esdsink
* @see_also: #GstAlsaSink, #GstAutoAudioSink
*
* This element outputs sound to an already-running Enlightened Sound Daemon
* (ESound Daemon, esd). Note that a sound daemon will never be auto-spawned
* through this element (regardless of the system configuration), since this
* is actively prevented by the element. If you must use esd, you need to
* make sure it is started automatically with your session or otherwise.
