Audio Player Suffering

I am a newbie at WordPress and desperately searching for a way to put flash player on my posts. After reading loads of discussions..etc on how to get this working I ended up installing Audio Player. Also uploaded couple tunes in my media library in order to test. But no chance. Each time I try to insert the tune in a post; all I have is an empty flash box on my post. How do I deal with it?

Any help would be highly appreciated!

Thanks in advance!
