Recently I wanted to burn an old, classical Audio CD (yes, you read right) from a MP3-Album purchased via Amazon MP3 (which is an amazing service btw).The reason is simple:I wanted to listen to the music in my living room, where only a rather old CD/DVD player does his job - not MP3 enabled or anything else.

I am really happy with K3B under Ubuntu - the best burning tool I ever had (better than all GNOME tools I tried, the KDE based K3B is not really beautiful when you're a gnome user but its beautiful that it "just works").

 So - started K3B - "new audio cd project"- wanted to drag some mp3s to the disc :"error" -- KDE denied to make the audio CD from MP3s because of some codec issues (codec issues again - the achilles heel of ubuntu/linux).

but after some googling I found a quick and easy solution - it is simply required to install a codec package:

sudo apt-get install libk3b6-extracodecs

and thats it! -- works perfectly!!!
