Dell Studio xps 16 ,No sound in Ubuntu

Dell Studio xps ,has a problem with sound in Ubuntu.

Actually machine detects the sound card properly

but cannot hear the sound.So you have to manually

edit the following file

Go to your Terminal and type:

$sudo gedit /etc/modprobe.d/alsa-base.conf

Then add following line at the end of the file

options snd-hda-intel model = dell-m6

Then reboot the system

When next Login you will hear the Ubuntu Login sound

Thank you
