    Can you describe that a bit better? Sound from speakers are supposed to stop when you connect headphones. I presume you mean something else.

    Can you provide information specific to your sound hardware/configuration?

    To do that, with your PC connected to the internet, can you also run (copy and paste) the following two scripts in an xterm/konsole and post the URL that they provide:
    Code:
    wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && bash alsa-info.sh
    for the next script when prompted for a password enter your root password, and type "NO" for every question that you don't undertand
    Code:
    su -c 'wget -O tsalsa wget http://home.cfl.rr.com/infofiles/tsalsa && bash tsalsa'
    and paste here the URL that these scripts will provide.

    Sorry I didn't gave mor detail. When I connect the phones, the laptop speakers immediately turns off, and the sound goes to the phones. There's when the phones sound starts to slowly fade out, until i can hear no sound, with all the KMIX levels up. At that moment,if I disconnect the phones the laptop speakers wouldn't give me sound either. I've seen that if I disconnect the phone when the sound is fading out the laptop speakers work, but at the same volume the phones were working at the time of the disconnection.

    I note the following
    Amixer contents for card 0 [Intel] _____________________________________
    amixer set 'Master',0 24% on
    amixer set 'Headphone',0 100%,100% on
    amixer set 'Headphone as Line Out',0 off

    amixer set 'Digital Input Source',0 Items: 'Analog Inputs' Item0: 'Analog Inputs'
    Should your headphone line out be OFF?

    I want that, in case it is necessary to propose a change to that file.

    Here it is

    options snd slots=snd-hda-intel
    # u1Nb.VhUtPypIg0D:82801H (ICH8 Family) HD Audio Controller
    alias snd-card-0 snd-hda-intel

    Thanks.

    Concerning to the phones output levels there's a screenshot.

    OK, thanks. Your Dell Inspiron 1525 is a bit of a tough nut to crack because it is fairly new, and its hardware audio codec conexant 2c06 is not well documented and possibly not well supported.

    I noted a Ubuntu user had to get a Dell/Ubuntu specific built "backport" package from Dell to get full functionality:
    Running Ubuntu 7.10 (Gutsy Gibbon) on a Dell Inspiron 1525 | Welcome at nain
    I would avoid that approach for now.

    I noted an openSUSE-10.3 user obtained partial functionality by using (custom compiling) very cutting edge tarballs from openSUSE alsa developer tiwai:
    GNU/Linux on a Dell Inspiron 1525 - nothingisreal.com
    ... thats another approach that is viable, but best not followed just yet.

    Instead, I recommend you edit your /etc/modprobe.d/sound file with this:
    Code:
    options snd slots=snd-hda-intel
    # u1Nb.VhUtPypIg0D:82801H (ICH8 Family) HD Audio Controller
    alias snd-card-0 snd-hda-intel
    options snd-hda-intel auto
    and restart your alsa with rcalsasound restart and test your audio. Does that help?

    If that doesn't work, in the /etc/modprobe.d/sound file replace "auto" with "3stack". Restart your alsa with rcalsasound restart and test your audio. Does that help?

    If that doesn't work, then you could update your alsa to the latest rpms. But I am not confident of that approach, as there is no mention in the alsa web site of any update to the conexant alsa driver since 1.0.16. Anyway, you can update alsa by copying and pasting and executing the following from an xterm/konsole with root permissions, one line at a time:
    Code:
    zypper ar http://download.opensuse.org/repositories/multimedia:/audio/openSUSE_11.0/ multimedia
    Code:
    zypper install alsa alsa-utils alsa-tools alsa-firmware libasound2
    Code:
    zypper rr multimedia
    Code:
    zypper ar http://download.opensuse.org/repositories/multimedia:/audio:/KMP/openSUSE_11.0_Update/ multimedia
    Code:
    zypper install alsa-driver-kmp-default
    Code:
    zypper rr multimedia
    Note - if any of the above fail, jump to the last command (removing the repos) and stop.

    Then restart your pc and test your audio. And again try the different model options in your /etc/modprobe.d/sound file

    And finally if that doesn't work, you could try a custom compile of the cutting edge tarballs mentioned here:
    GNU/Linux on a Dell Inspiron 1525 - nothingisreal.com
    where the tarballs are here:
    Index of /pub/linux/kernel/people/tiwai/snapshot
    If you go that route, you are very much on your own as to which tarball you select and build. I have no knowledge of that site.

    I was reading the openSUSE-10.3 user's post, and he claims his Dell Inspiron 1525 has a stac9228. I am thinking yours does not. .. Hence that may not work. But if by chance it IS a stac9228 that has been inappropriately identified, then in addition to trying the model options "auto" and "3stack", you could also try "5stack" and "dell-3stack" as those are valid stac9228 options. Don't forget to retart alsa after each attempt.

    Good Luck.

    From ALSA-Configuration.txt file:
    Code:
    	STAC9227/9228/9229/927x
    	  ref		Reference board
    	  3stack	D965 3stack
    	  5stack	D965 5stack + SPDIF
    	  dell-3stack	Dell Dimension E520

    	  dell-3stack	Dell Dimension E520
    Your conexant 2c06 on a Dell was reminding me of something I could not remember/place, ... so I did a search and found a post in the archives where a user applied the "dell-3stack" model option to their /etc/modprobe.d/sound file and it worked:
    Dell Vostro1400 ; Hda Intel; ... No Sound - openSUSE Forums

    So definitely give that some consideration.
