hi. recent convert to unbuntu/kubuntu and was looking for help on audio support. i've downloaded all of the libraries that i can find for mp3 support. my DRM protected itunes purchased tracks no longer work on my ipod and i have just cast them away. I recently purchased a Sandisk Sansa Express flash mp3 player that seems to work well. Only problem seems to be that i cannot load tracks onto it that i have ripped myself. The tracks were ripped under windows which is no longer installed on my computer and are in the m4a format. i cannot find a way to convert them to ogg's, mp3. I thought i would burn the m4a's onto cd and then rerip them but K3b will not burn the m4a's despite Amarok's recognition of the files. Any help on libraries/programs to solve this quandary?
