Bug Description
Dell Latitude E5520 has sound through headphone jack but no sound through built-in speakers on Ubuntu 10.04.2 and 10.10
Dell Latitude E5520 contains the following sound controller (output from lspci):
Audio device: Intel Corporation Cougar Point High Definition Audio Controller (rev 04)
PCI ID: 8086:1c20
Problem can be solved by installing linux-alsa-
Sound works fine with Ubuntu 11.04, so installing linux-image-
SOLUTION for Ubuntu 10.04 LTS: Please update linux-backports
ALSA 1.0.24 released on 2011-01-30, see http://
I found a similar bug #582506 but with different audio hardware. I think the latest ALSA drivers would fix that bug also.
