k3b cannot deal with mp3 files by default in Ubuntu Edgy Eft.
If you need to produce an audio cd by adding mp3 files with k3b, you’ll need to install the following package:
sudo apt-get install libk3b2-mp3
and you are done!!

HOWTO: Recording audio cds with K3b
HowTo Ubuntu 8.10 64bit and Areca 6.2 (6.1) java Backup Utility
1) Go to Synaptic and install
libswt-cairo-gtk-3.4-jni
libswt-gnome-gtk-3.4-jni
libswt-gtk-3.4-java
libswt-gtk-3.4-jni
libswt-mozilla-gtk-3.4-jni
2) cd /usr/lib/jni
cp the files:
libswt-atk-gtk-3448.so
libswt-cairo-gtk-3448.so
libswt-gtk-3448.so
libswt-pi-gtk-3448.so
libswt-awt-gtk-3448.so
libswt-gnome-gtk-3448.so
libswt-mozilla-gtk-3448.so
to the areca/lib folder with names in order of appearance:
libswt-atk-gtk-3232.so
libswt-cairo-gtk-3232.so
libswt-gtk-3232.so
libswt-pi-gtk-3232.so
libswt-awt-gtk-3232.so
libswt-gnome-gtk-3232.so
libswt-mozilla-gtk-3232.so
overwriting the original ones 
.
3) the files:
org.eclipse.swt.gtk.linux.x86_3.2.0.v3232m.jar
org.eclipse.jface_3.2.0.I20060605-1400.jar
come from an eclipse installation actually, so if you don’t have eclipse,
download it and:
cd eclipse/plugins
and cp the org.eclipse.swt.gtk.linux.x86_64_3.4.1.v3449c.jar
into areca/lib org.eclipse.swt.gtk.linux.x86_3.2.0.v3232m.jar
and cp org.eclipse.jface_3.4.1.M20080827-2000.jar to areca/lib
org.eclipse.jface_3.2.0.I20060605-1400.jar
overwriting the original ones.
Now, the file libarecafs.so surprise, surprise is a 32 bit one, so I compiled the 64bit one.
With the 32bit one, you’ll get a couple of warnings:
09-01-22 20:44 – WARNING – com.myJava.file.metadata.posix.jni.JNIMetaDataAccessor cannot be used on this system. Got the following error : “java.lang.UnsatisfiedLinkError : /home/jordilin/areca/lib/libarecafs.so: /home/jordilin/areca/lib/libarecafs.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)”
09-01-22 20:44 – WARNING – [com.myJava.file.metadata.posix.jni.JNIMetaDataAccessor] not validated. The default metadata accessor will be used instead.
4) ./areca.sh
5) done
Note. I tested this using 6.2 pre-release, but using 6.1 should be the same.

Ubuntu 9.04 (Jaunty Jackalope) Final
Ubuntu is a community developed, linux-based operating system that is perfect for laptops, desktops and servers. It contains all the applications you need – a web browser, presentation, document and spreadsheet software, instant messaging and much more. Ubuntu is free software. Whether you use it at home, at school or at work Ubuntu contains all the applications you’ll ever need, from word processing and email applications, to web server software and programming tools.
Ubuntu is and always will be free of charge. You do not pay any licensing fees. You can download, use and share Ubuntu with your friends, family, school or business for absolutely nothing. We issue a new desktop and server release every six months. That means you’ll always have the the latest and greatest applications that the open source world has to offer. Everything you need on one CD, which provides a complete working environment. Additional software is available online.
Ubuntu comes with full commercial support from Canonical and hundreds of companies around the world. Ubuntu includes the very best translations and accessibility infrastructure that the free software community has to offer. Ubuntu CDs contain only free software applications; we encourage you to use free and open source software, improve it and pass it on.
With Ubuntu Desktop Edition you can surf the web, read email, create documents and spreadsheets, edit images and much more. Ubuntu has a fast and easy graphical installer right on the Desktop CD. On a typical computer the installation should take you less than 25 minutes. The graphical installer enables you to get up and running quickly and easily. On the desktop you have a full set of productivity, internet, drawing and graphics applications, and games.
The Server Edition – built on the solid foundation of Debian which is known for its robust server installations — has a strong heritage for reliable performance and predictable evolution. As your business grows, so does your network. More applications need to be deployed and more servers are required. Ubuntu Server Edition offers support for several common configurations, and simplifies common Linux server deployment processes. It provides a well-integrated platform enabling you to quickly and easily deploy a new server with any of the standard internet services: mail, web, DNS, file serving or database management. A key lesson from its Debian heritage is that of security by default. The Ubuntu Server has no open ports after the installation and contains only the essential software needed to build a secure server.
