Further testing I've made showed different results. I've downloaded the source code of pulseaudio in Vivid
$ apt-get source pulseaudio
then I compiled the pulseaudio-6.0/po/el.po , WITHOUT change anything and I replaced the pulseaudio.mo with the new compiled pulseaudio.mo.
Guess what, audio works.
So, maybe something is going on with the Machine Object file and has nothing to do with translation ?
