headphones jack doesn't mute speakers on lenovo 3000 n100

I have the same issue on a Lenovo 3000 V100 running feisty, and google search suggests that other laptops using the chip have the same issue.

Any chance this could be fixed in feisty?

I can confirm this using Ubuntu 6.10 Edgy Eft with an N100 0768-6KU.

I own the same laptop and can confirm this bug is alive in Feisty.

I have an HP pavilion dv2000z with the same audio chip. The problem was fixed in kernel 2.6.20-10 on feisty but came back in the kernel revisions after that

I have same problem with HP Pavilion dv9297ea but I have a workaround (see laptop testing page, community supplied laptops for full report).

Basically, press mute, plug in phones, then unmute. sound comes through phones and not main speaker. To reverse, press mute, unplug phones, then unmute...sound now comes through main speakers again.

I just tried the mute/unmute trick. Does not work on my computer

it is the same here, this workaround doesn't work.

Is this the same as Bug #94566, which should be fixed with the new kernel 2.6.20-14.

Doesn't work for me.

I'm going to try compiling alsa by hand with the patch to see if that fixes the issue

Well I can say that Bug#94566 was not fixed in the new Kernel 2.6.20-14, it hasn't yet been fixed in feisty.

I had no problems on feisty since some time (with Lenovo N100), but on 2.6.22-3 on Gutsy the problem is back. *SIGH*

On feisty since few days (maybe since the last update of the kernel from security) the bug came back ...

Problem persists: Toshiba P205 with intel hda. Gusty tribe 2, alsa-base 1.0.14-1ubuntu1, kernel 2.6.22-7-22 generic

Update on Toshiba satellite P205:

After recent update of Ubuntu the problem seems to be solved.
2.6.22-9-generic (package version 2.6.22-9.25)
alsa-base 1.0.14 (package version 1.0.14.1ubuntu1)

File ' /etc/modprobe.d/alsa-base' contains the following line:

options snd-hda-intel model=lenovo

How it's working now:
 * Muting 'front' channel mutes the speakers
 * Changing 'front' level (volume) with volume weel un-mutes the speakers
 * Plugging headphones into the front jack mutes the speakers
 * Unplugging the headphones un-mutes the speakers
 * Checking 'headphones' mixer option actually gives sound to the front jack

Mic, front mic, mic boosts also work as intended.

I'm marking as related to 2.6.22 because I had problems with it, however in linux-image-2.6.22-10-generic version 2.6.22-10.30 the problems got considerably worse, as noted in bug #134125. At least in -10 I tested the "model" switch and it didn't help.

Confirming: 2.6.22-10 breaks the achievements of 2.6.22-9. Seems like the model parameter to snd_hda_intel do not take effect anymore.
On my Toshiba Satellite P205 with 2.6.22-9, model="lenovo" everything worked 100% OK. PLZ don't let it crawl into the release!!!

Seems that a lot of people have the same problem. +1 on Dell Inspiron 640m with Intel's ICH7

The broken 2.6.22.10 is discussed here:
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/134146
There is a solution that seems to work, BTW.

seems to be related to the AD198x Analog chipset. +1 for hp nx6325

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!
