I have a collection of devices managed usign Windows Media Player.
WiMP is a good media manager, but it does have its quirks, like occasional Chernobyling of the music database. Since WiMP is available on most computers, it’s natural that I tread the waters and work with it.
WiMP will communicate with your Sansa in either MSC or MTP mode, but MTP is designed to see the Sansa as a Media Device. If you’re using Windows Media Player and MTP, there are two different methods of “synchronizing your music”. WiMP’s interface shows them both as “sync”.
I wish the manual method would more clearly display as “transfer” rather than “sync”.
You can drag music files to the “sync list” on the right, then transfer them over by pressing Sync. The other method is automatic sync, where you set up the device for transfer. This is available via the drop down menus at the top of the interface. Look for Set Up Sync. (The WiMP12 interface is a little more tricky than WiMP11, which had a little bar at the bottom of the Sync button.)
Each device should be recognizable as a unique device by WiMP. If this is messed up, you can delete the file wmpinfo.sys from the Sansa’s root directory, then Set Up Sync over again on the PC. Remember, remove those nasty “all” choices like “all TV episodes”, “all video”, “all music”, etc, lest WiMP try and fill your Sansa to the brim. If WiMP does “max out” your device, fear not! Simply leave the device connected, run Set Up Sync again, and REMOVE those choices. Click Sync once again, and WiMP will pick up the pieces automatically.
