I am trying to compile and install the a52 plugin following the instructions from here:

https://help.ubuntu.com/community/DigitalAC-3Pulseaudio

This worked on Ubuntu 11.10 but gives me some errors when I try to compile the plugin on Ubuntu 12.04. I've searched for a solution however I couldn't find much on this topic in general, not to talk about a solution. I would really appreciate some help on this:
