Description:

def libvlc_audio_set_mute(p_mi, status):
    '''Set mute status.
    @param p_mi: media player.
    @param status: If status is true then mute, otherwise unmute @warning This function does not always work. If there are no active audio playback stream, the mute status might not be available. If digital pass-through (S/PDIF, HDMI...) is in use, muting may be unapplicable. Also some audio output plugins do not support muting at all. @note To force silent playback, disable all audio tracks. This is more efficient and reliable than mute.
