Headphones and laptop speakers work simultaneously

[Sykand3r]

When I plug in my headphones, the speakers don't go off. I have Ubuntu 8.04, updated, installed on MSI EX600.
I ran a search thru the answers posted here, but none did solve my problem.

not a gnome-volume-manager issue.

Hi this is the first time I use launchpad, I hope I use it correctly if not I apologize.

I have the same problem.
I have ubuntu 8.10 (intrepid)
kernel linux 2.6.27-9 generic
Gnome 2.24.1
on a
ASUS U1 ultra SLIM

When I plug in my headphones, the speakers don't go off

it is a real problem for me as I need to talk over skype and the whole family must hear to my conversations. What can I do?
p.s.
I attach buginfo. txt I obtain with
(echo '== Sound cards ==' && cat /proc/asound/cards && \
echo && echo '== aplay -l ==' && aplay -l && echo \
&& echo '== lspci =='&& lspci) > ~/buginfo.txt

You might try the various model option for the intel sound driver for your codec. From the alsa documentation:

        ALC861VD/660VD
          3stack 3-jack
          3stack-dig 3-jack with SPDIF OUT
          6stack-dig 6-jack with SPDIF OUT
          3stack-660 3-jack (for ALC660VD)
          3stack-660-digout 3-jack with SPDIF OUT (for ALC660VD)
          lenovo Lenovo 3000 C200
          dallas Dallas laptops
          hp HP TX1000
          auto auto-config reading BIOS (default)

You can try these as a model=3stack etc in /etc/modprobe.d/alsa-base, adding a line like this:

options snd-hda-intel model=3stack

You would need to reboot to try each of these.

Just to make sure I understand.
I have to add at the end of /etc/modprobe.d/alsa-base

options snd-hda-intel model=3stack
save and reboot and try
if it does not work I add instead
options snd-hda-intel model=3stack-dig
and so on until it works.

I have tried 3stack, 3stack-dig, and auto. None of these 3 work. I have also installed Gnome Alsa Mixer.
For me it would be ok to disable the PC speakers for ever.
I will continue with 6stack-dig,
          3stack-660
          3stack-660-digout
          lenovo
          dallas
          hp
if I am doing right.

It might be off-topic, but I have a related problem with HP 2530p and Xubuntu 9.04:
with the default settings, I have sound only in headphones, the speakers do not work.
Then I followed http://www.linlap.com/wiki/hp+elitebook+2530p and added
options snd-hda-intel enable_msi=1
options snd-hda-intel single_cmd=1
options snd-hda-intel model=laptop
to /etc/modprobe.d/alsa-base.conf

With this config, I get the above problem, i.e. that speakers work all the time, regardless whether headphones are connected or not. I tried severeal different models (auto, hp, 3stack, 3stack-dig, laptop-hp), but 'laptop' is the only one that seems to make any difference.

Is there some other model I should have tried?

Thanks,
Michal
