Last night I purchased a Zen X-Fi by Creative. It's an MTP device, and I love it so far. It took me awhile to figure out how to make it talk to my computer and getting it to the point where Amarok would see it.

Unfortunately when I connect it and start up Amarok, Amarok fails to see all of the tracks that I've transferred to it. It shows some, but not all of them, even to the point where if I sync a playlist, it will duplicate tracks on my device.

Is anyone aware of this sort of issue, and how I might fix it?
