* The non-empty audio state handler is used to send a DBus signal when the
* system-level non-empty audio state changes.
* cras_non_empty_audio_msg() is called from audio thread to update the
* non-empty audio state in the main thread, which in turn sends the DBus
* signal.
* cras_non_empty_audio_handler_init() is used to setup the message handler
* in the main thread to handle the non-empty audiomessage from audio thread.
