Hi everybody,

I have a HP dv6 laptop running Ubuntu 9.04 Jaunty, with the same lspci
-v output as soisenpaix:

00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
        Subsystem: Hewlett-Packard Company Device 3061
        Flags: bus master, slow devsel, latency 64, IRQ 16

        Capabilities: <access denied>
        Kernel driver in use: HDA Intel
        Kernel modules: snd-hda-intel

01:00.1 Audio device: ATI Technologies Inc R700 Audio Device [Radeon HD 4000 
Series]
        Subsystem: Hewlett-Packard Company Device 3061
        Flags: bus master, fast devsel, latency 0, IRQ 19
        Memory at d2310000 (32-bit, non-prefetchable) [size=16K]
        Capabilities: <access denied>
        Kernel driver in use: HDA Intel
        Kernel modules: snd-hda-intel

I had no sound with Ubuntu's default installation. After reading other
distro's forum, the only solution I've found so far is to update the
ALSA driver and configure it for an HP dv5 laptop.

1) Open a Terminal and type:
     sudo apt-get install kernel-package
2) Go to the ALSA project web page http://www.alsa-project.org/  and download 
the latest ALSA driver. Currently is 1.0.20.
3) Uncompress the file (double click). Go to the folder created, build and 
install the driver. Briefly, type in a Terminal:
    cd Desktop/alsa-driver-1.0.20/                                        
remember you can use TAB to auto complete
    ./configure
    make
    sudo make install
4) Configure the ALSA driver. Type in a Terminal:
    sudo echo -e "alias snd-card-0 snd-hda-intel \noptions snd-hda-intel 
model=hp-dv5 \nalias sound-slot-0 snd-hda-intel"  >>  
/etc/modprobe.d/alsa-base.conf
5) Reboot.

I know we are using HP dv6 and dv7, not dv5, and the sound is below the
hardware's capacity, but at least it works. The Gnome volume controls
don't work, so I need to use the volume control from elsewhere.
