Rubygame on rails : Support of audio formats(mp3, ogg) while using Rubygame gem on Rails

I have tried support of midi, mp3, ogg, aiff and wav files on ruby interpreter after installing rubygame and it works fine. I Used the Rubygame::Music class and methods in it for the same.

But when i use and try it on the rails framework only mid开发者_开发知识库i format is working and the rest of the formats(mp3, ogg, aiff and wav) are getting executed but there is no sound.

After some googling i saw this : http://blog.rubygame.org/2008/04/01/rubygame-on-rails/ As per it, "Currently, the only audio support in RGoR (Rubygame over rails) is playing MIDI versions of 1990′s pop songs.However, I hope to fix these and other issues in future releases."

Is this fixed now on latest versions and has anyone tried these formats(mp3, ogg) on RGoR?
