Can't import MP3 in AVIDEMUX?

[Dojan5]

This is quite annoying...
Im using Avidemux.
I have cut together a movie, the only thing left is to add sound.
For some reason it wont add any music when i click Audio > Main Track then i choose External Mp3 File. Opens the file and presses OK.
Nothing become added... Why not?
Is there any other way to add sound?
Another program?
Help please. Im going to upload it to YouTube so, it will be hard to add a soundtrack to the video if you dont have the song....
Thanks

Have you made sure you have all the necessary MP3 Codecs installed, MP3s took me a while and there are quite a few gstreamer plugins needed. I found that they all seem to be dependencies of the ffmpeg (http://packages.ubuntu.com/gutsy/graphics/ffmpeg) package on the packages.ubuntu.com (http://packages.ubuntu.com)

Hope this helps.:)
