The sound was working.. and now its not.

I've tried:

sudo alsa force-reload

sudo apt-add-repository ppa:ubuntu-audio-dev/alsa-daily 
sudo apt-get install oem-audio-hda-daily-dkms

pulseaudio --kill; sleep 2s; sudo alsa force-reload ; 
pulseaudio --start

bios->disable audio -> boot to ubuntu -> restart -> bios -> enable aduio -> boot to ubuntu

Outputs:

pacmd list-cards
0 card(s) available.
