    Gentoo XPS Headphone Jack


    I posted this on Hardware forum, but no answer came. So I think its apt to post it here now:
    Friends,
    My Dell Studio XPS 16 laptop has two headphone jacks.
    In Vista:
    -> Jack 1 behaves normally, the laptop speakers are blocked and audio is routed to the headphone.
    -> Jack 2 doesnt mute the speakers and both the headphone and the speakers work simultaneously.
    I guess this is what is expected, you can actually plugin two hedphones simultaneously and both would work.

    Now in Linux (Gentoo 2.6.27):
    -> Jack 1 blocks the laptop speakers, and no sound in the headphone too. It mutes everything.
    ->Jack 2 behaves like it does in windows -> both speakers and headphones work.

    Output of aplay -l :
    \**** List of PLAYBACK Hardware Devices ****
    card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog]
    Subdevices: 1/1
    Subdevice #0: subdevice #0
    card 1: HDMI [HDA ATI HDMI], device 3: ATI HDMI [ATI HDMI]
    Subdevices: 1/1
    Subdevice #0: subdevice #0

    And yes nothing is muted in alsamixer.
    alsamixer -c 1 (card 1) is a bit strange though.. has only one bar IEC958, and theres no bar actually to change the volume.
    alsamixer -c 0 has lots of bars, but the headphone bar doesnt effect the volume of headphones plugged (even in jack 2).

    I have tried a lot but cant fix it, I cant use my headphone at all and its very annoying. Please help me.

    Thanks
