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?
