Did M3U playlisting work properly with a previous firmware build? Sorry, but for my own playlist needs, MTP mode has been the mode of choice, since I use the players with Rhapsody and Audible services, so I’ve remained primarily in this mode, using PLA format lists.
If there was a firmware build prior to the 18 version currently available, in a few minutes’ time,the previous firmware can easily be reinstalled, if it will help your issue.
Here isversion 01.01.15 for example. Click on the link, and follow the manual installation instructions.
I am certain that playlist compatibility will be corrected in a future release, but you can revert to any prior version at will if desired. One of the coolect things with the Sansa is that it allows this.
