Comment 17 for bug 106843

It Works!!!!! I was missing the alsa-base file. Then I found a work-around from bug #83015 as follows:
1. edit alsa-base:
sudo gedit /etc/modprobe.d/alsa-base

2. add this line to the end of that file:
options snd-hda-intel model=3stack

3. save y close the file

4. restart
