ubuntu 10.04 Amarok can't find music

Did you install the support for MP3 ? That could be the reason. If you simply double click on a MP3, can it play it? If it cannot, it should offer you to install the missing codec I think.

When I first started program, I set the preference as the music folder in my external hard drive. The program showed down the bottom that it was scanning drive, but it just sits at 0%. One thing I did find is when I went into preferences again to check my folder settings, I opened up the next level in the drives music folder, where all the individual artists folders are, and they were all grayed out and unselectable. Could this mean something? Is there some mp3 codec I am missing, and if so, how do I install it?
Hope this extra info helps.

Double click a MP3 in the file browser. It should open it in Totem, and if the MP3 codec is missing, it should offer you to install it.

I did as suggested and it installed mp3 codec. Opened Amarok and tried to play mp3, it recognized it, but wouldn't play it. I found a help page that said to install in terminal - "sudo apt-get install libxine1-ffmpeg gstreamer0.10-plugins-ugly" and also
"sudo apt-get install kubuntu-restricted-extras" which worked in so far as the mp3 would now play. Tried to rescan my external drive, still just sat there at 0% and "scanning". Frustrating is an understatement.

Yes, does not sound easy... It's not a codec problem.

I think you may know more by running Amarok from a terminal. Open one from the accessories, then type "amarok". Scan for your mp3s. Then check in the terminal if anything interesting is displayed.

Tried running amarok in terminal, this is what came up -

Don't know if this helps.

I finally sorted problem out, added some other packages, and it worked.
