Public bug reported:
Hello,
I've just installed Ubuntu 10.04 and there is no sound in the front jack. The
sound works fine in the back jack.
The problem is that the front jack works fine from the live CD. I have
done some tests, and all the sound modules (snd*) are the same in the
live CD and in the installed version, all the parameters (modinfo) are
the same too, but the front jack only works in the Live CD.
The only difference that I see from the live version from the installed
one, is that the live version has some modules that are not loaded in
the installed version. They are: aufs, dm_crypt, dm_raid45, drm,
drm_kms_helper, fat, isofs, nls_cp437, nls_iso8859_1, nouveau, squashfs,
ttm, vfat, xor. But I think that these modules are not related to sound
issues.
The installed version has the nvidea module, but the sound also wasn't
working before the installation of the nvidea driver.
My motherboard is asus M2N68. This problem occurs not only with the
2.6.32-23-generic kernel but also with the 2.6.32-21-generic kernel (the
live version uses the 2.6.32-21 version)
The output of the alsa-info.sh script can be found in:
Live version:
http://www.alsa-project.org/db/?f=1fb4ce3c69fa0d7e6c046d6acbd164bd2c536000
Installed version:
http://www.alsa-project.org/db/?f=b5d080eb46cff9f63c2a302d69ca86ff095ad4bb
I can send more information to investigate this bug.
Cheers,
Pedro
