> If confbridge is configured with *announce_join_leave* option set to _yes_, it records announcements with names of entering users and then plays them while users enter or leave the conference.
> When user leaves a conference, its channel calls *async_play_sound_file()* function in order to play the name announcement and then unlinks the sound file with _ast_filedelete()_. The _async_play_sound_file()_ function adds a task to conference playback queue, which then runs _playback_common()_ function in a different thread. It leads to a race condition when in some cases the channel thread may unlink the sound file *before* _playback_common()_ had a chance to open it.
> If that is the case the announcement is not played and CLI contains two warnings:
