My answer was wrong. When you say the complete audio novel, you mean that there will usually be sound when the audio book is played. If the playback fails, the sound may be interrupted. If the audio book fails to play, it may be because the device does not support the format or it needs to be downloaded or installed again. If you want more detailed help, we suggest you check the relevant documents of the equipment or software you are using or consult the relevant technical support personnel.
