Hello,
Not sure if you’ve finally solved this problem. And I’m not sure if this is the right solution I just found it by mistake. Have noticed that when I add new mp3 song to my folder (I used folders instead of playlst still haven’t worked that out yet 
) unless I choose random play the latest songs will only be played at the end. So I tried this with the audio books. Create folder e.g. Lauren Willig - That Summer and added the chapters one by one into the SanDisk starting from Chapter 1 and so on. Don’t be tempted to add more a a time as the order will be scrambled again. It’s tedious I know but well worth it. Somehow the San Disk is programmed to play according to the time when the files were added. In this case the earlier files are played first regardless of the titles… But if it’s somewhere in the settings maybe you can have a look at that too.
