12.04 - How to install pulseaudio 5 on Ubuntu - Ask Ubuntu
https://askubuntu.com/questions/444457/how-to-install-pulseaudio-5-on-ubuntu
Ubuntu 12.04 is a bit old to install PulseAudio 5, even 14.04 will ship PulseAudio 4, see the dedicated package page. If you really need the latest version, I would rely on the PulseAudio testing ppa , which provides a properly packaged version of PulseAudio 5 for 14.04:
System-Wide PulseAudio Equalizer Updated For Ubuntu 16.10 ...
http://www.webupd8.org/2013/10/system-wide-pulseaudio-equalizer.html
The PPA now supports Ubuntu 16.10, 16.04, 15.10, 15.04, 14.04 and 12.04, as well as Linux Mint 18 and 17. The package update comes with a fix for a crash that occurred when no presets were found. The issue that caused audio to be muted as soon as PulseAudio Equalizer was enabled, disabled, or adjusted, was also fixed.

Install Pulseaudio With Built-In System-Wide Equalizer In ...

I expect the equalizer to work better in Ubuntu 13.04 (since Raring has Pulseaudio 3.0 while Quantal has 2.1 and Precise 1.1 and thus, older equalizer, etc.) and indeed it has worked great in my test under Ubuntu 13.04 but I've also performed a quick test in Ubuntu 12.10 and 12.04 and I didn't notice any issues.

It is very unlikely that a bug was fixed a year ago, was provided with up-to-date drivers from the ubuntu-audio-dev ppa, but did not make it for the release in 12.04. LTS. Therefore I suggest you first have a look whether your /etc/pulse/daemon.conf is set to enable 2.1 sound.
