The new Ubuntu isn’t doing all so well with media playback at all.
First of all all programs that are supposed to be able to handle my iPod can’t write the media database anymore (they had no problem syncing it before, but then after an ugly crash i had to factory reset it, and since then, nothing). They add/delete the files alright, but they’re unable to do anything with the database, resulting totally useless gigabytes of data on the player.
