[Bug 1679462] [NEW] Secure boot disable audio

[Cristhian Quiñonez]

Public bug reported:

I'm new in Ubuntu 14.04, yesterday everything was working okay in my
computer until I updated ubuntu. the software center just showed up and
asked me for install new stuff, so I said yes. After the updates
finished and the computer restarted, the sound of my computer stop
working, I have tried everything. Install, purge, upgrade, reinstall
alsa, install the driver of sound, anything worked.

The only thing that worked was to disable the secureboot. But it shows
de message “Booting in insecure mode ", i decided to enable secure boot
again and the sound is not working.

What is happening if everything was fine until I updated Ubuntu?

I have an Inspiron 14 (3459)
