Previous I have never used rhythmbox by default because it seemed to be lacking in features to me. Just my personal opinion.
With rhythmbox back in 12.04 will ubuntu give it some attention to give it some usability one thing that was majorly missing on my last use of rhythmbox was an equalizer which is the most basic of requirements for an audio player let alone a preamp.
I have searched and found that on the rhythmbox website the plugin is available but in the plugins menu of rhythmbox it is not there.
I searched google and there are many guides from 2009 trying to install the equalizer. there is nothing recent and one would assume this would be a default plugin, there is no point after all searching for cover art if your music doesn't sound right.
How can I easily install the equalizer in 12.04?
