    HP DV7-4177CA Laptop Subwoofer not Playing Sound in Ubuntu 10.04.2 LTS 64-Bit

    Hello
    There is an issue that has gotten annoying.
    My laptop plays sound fairly nicely, however the subwoofer does not play anything!
    Now i am a complete linux noob, so any help on this would be greatly apprectiated.
    I have the beats audio on this system if that helps at all.
    TIA

    I got it working, after a long search I've found this on a HP forum:

    http://h30434.www3.hp.com/t5/Noteboo.../617837#M60631

    Basically you only have to open alsa-base.conf:

    sudo gedit /etc/modprobe.d/alsa-base.conf

    ..and add the following line:

    options snd-hda-intel model=ref

    Save. Reboot.
