Perhaps if you told us what you've tried, where it fails, and anything about your configuration (like version/distro of Linux, and what kind of hardware), someone could help you.
Since it works in some things, chances are whatever Firefox plugin you're using for media, isn't working right. And you don't say what file(s) you're playing through Amarok, but alot of distros don't ship with MP3 support built in by default...you have to install the codecs.
