    headphones doesn't mute speakers

    Hello everybody,
    I have ASUS F3Ka laptop. I have installed both Win7 & Ubuntu 9.10
    unfortunately when I'm using Ubuntu the system doesn't recognize my headphones and plays the sound from speakers & headphones at the same time... This is an information of my sound card:

    laptop:~$ cat /proc/asound/card0/codec#* | grep Codec
    Codec: Realtek ALC660-VD
    Codec: Motorola Si3054
    laptop:~$ aplay -l
    **** List of PLAYBACK Hardware Devices ****
    card 0: SB [HDA ATI SB], device 0: ALC660-VD Analog [ALC660-VD Analog]
    Subdevices: 1/1
    Subdevice #0: subdevice #0
    card 0: SB [HDA ATI SB], device 1: ALC660-VD Digital [ALC660-VD Digital]
    Subdevices: 1/1
    Subdevice #0: subdevice #0
    card 0: SB [HDA ATI SB], device 6: Si3054 Modem [Si3054 Modem]
    Subdevices: 1/1
    Subdevice #0: subdevice #0

    Any suggestions?
    p.s. sorry for my English.

    Try this. Open a terminal ("Applications>Accessories>Terminal). Enter this command:
    gksudo gedit /etc/modprobe.d/alsa-base.conf
    At the bottom of that file add this line:
    options snd-hda-intel position_fix=1 model=lenovo
    Save. Close. Reboot.
