    no sound

    I have a new Dell XPS 9100 with 9GB ram and ATI Radeon HD 5770 1024MB GDDR5.
    I installed a dual boot with Windows 7 and Ubuntu 64bit. Sound worked fine with
    the Windows 7, but no sound with Ubuntu. Did a reinstall with just Ubuntu 64 bit (wiping out the Windows 7). No sound.
    I first did:
    System -> Administration->System Testing
    (testing only for sound). I get:

    0 [Intel ]: HDA-Intel - HDA Intel
    HDA Intel at 0xfbbf4000 irq 22
    1 [Generic ]: HDA-Intel - HD-Audio Generic
    HD-Audio Generic at 0xfbefc000 irq 17


    Next I followed: "Comprehensive Sound Problem Solutions Guide v0.5e"


    (1) aplay -l

    I get:

    *** List of PLAYBACK Hardware Devices ***

    card 0: Intel [HDA Intel], device 0: HDA Generic [HDA Generic]
    Subdevices: 1/1
    Subdevice #0: subdevice #0
    card 1: Generic [HD-Audio Generic], device 3: ATI HDMI [ATI HDMI]
    Subdevices: 1/1
    subdevice #0: subdevice #0

    (2) lspci -v

    I get

    (3) went to http://www.alsa-project.org/alsa-doc/
    Under ATI I get:

    Don't see the ATI HD 5700. I guess this is "Failure."

    Under Intel I get:

    I guess this is also "Failure"?

    Not sure what to do next....

    Help would be greatly appreciated.
    (I'm barely computer literate.)

    Thanks in advance ...

    Re: no sound

    Solved: it helps to plug the speakers into the correct jack.
