I would like to say that this might be more than just Intel. I'm experiencing this issue, with something HP calls "Integrated Realtek ALC 662".
The Live CDROM of Lubuntu 15.04, which boots under vmlinuz-3.19.0-15-generic gives me sound just fine. But when I installed, and did "apt-get dist-upgrade", bringing me up to vmlinuz-3.19.0-22-generic, there is no sound. So that should be an easy to understand path from "working" to "not working". Please note that Lubuntu is being hounded, by its users, for this sound issue.
