Recently I have upgraded my Ubuntu OS from 12.10 to 13.04 on my Dell XPS.
But suddenly I faced issue with my sound. I am not able to get sound form my machine.
After googling, I found solution for Dell Vostro, but after some time I found for dell xps too. I tried solution on my Dell box and my sound is back.
Here is the solution,
sudo gedit /etc/modprobe.d/alsa-base.conf
Add following line at the bottom of a file
options snd-hda-intel model=dell-bios
But don't forget to reboot your machine.
