Title:
[IDT ID 76e7] Dell Latitude E5520 - No sound through internal
speakers, sound is only from headphones output with Ubuntu 10.04.2 and
10.10 - update Lucid ALSA LBM to latest release (1.0.24)
Status in alsa-driver package in Ubuntu:
Invalid
Status in Baltix:
New
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-driver-modules-$(uname -r)
package from ppa:ubuntu-audio-dev or from Baltix GNU/Linux repository
(https://launchpad.net/~baltix-members/+archive/ ). Installing official
linux-backports-modules-alsa-lucid-generic package doesn't fix this problem :(
Sound works fine with Ubuntu 11.04, so installing
linux-image-generic-lts-backport-natty package from ppa:kernel-ppa also fixes
this problem.
SOLUTION for Ubuntu 10.04 LTS: Please update
linux-backports-modules-alsa-lucid-generic package to include the latest ALSA
drivers (1.0.24) from http://alsa-project.org or include
linux-image-generic-lts-backport-natty package into official Ubuntu 10.04
backports or updates repository.
ALSA 1.0.24 released on 2011-01-30, see
http://alsa-project.org/main/index.php/Changes_v1.0.23_v1.0.24 for list of
improvements.
I found a similar bug #582506 but with different audio hardware. I
think the latest ALSA drivers would fix that bug also.
