[Jimz Au]

lsb_release -rd gives:
------------------------------------------------------
Description: Ubuntu 10.04 LTS
Release: 10.04
-----------------------------------------------------

the headphones does not mute the speaker. I have tried ALL combinations to put in the /etc/modprobe.d/alsa-base.conf for the line:
                 snd-hda-intel model=xxx

I have tried to update the alsa-driver to 1.0.23 by following this website:
                 http://monespaceperso.org/blog-en/2010/05/02/upgrade-alsa-1-0-23-on-ubuntu-lucid-lynx-10-04/
however, after a reboot, the alsa-driver seems to revert back to 1.0.22.1 (see below)

It seems to be the Dolby Digital "subwoofer" that is not being mute...

The same problem: Lenovo G460, Kubuntu 10.04

BTW, here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/219556 (at the bottom), Isaia says about "Headphone" Channel in the alsamixer.. hm, I have to such channel.

Tried that, but I dont have such "Headphone channel" in alsamixer...

This is fixed in upstream ALSA. Should try out alsa-backports in proposed repository.

Are you referring to this package:
    linux-backports-modules-alsa-lucid-generic

My kernal is 2.6.32-23-generic and I am using Ubuntu 10.04, which is Lucid Lynx.

I have checked that I have installed this package and the other one, which is
    linux-backports-modules-alsa-2.6.32-23-generic.

But the problem is still there... Thanks for your input though =]
