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 ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1445358 Title: Pulseaudio fails to run when system's language is in Greek To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1445358/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
