Problema resolvido segue os ultimos passos que fiz para resolver:

Citar
sudo apt-get install build-essential
wget http://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/\
alsa-driver-unstable-snapshot.tar.bz2 -O -| tar xvj
cd alsa-driver-unstable
./configure --enable-dynamic-minors
make
sudo make install-modules

apos estas instalacoes tive de modificar algumas coisas no alsa

Citar
no terminal coloquei o seguinte comando> sudo gedit /etc/modprobe.d/alsa-base.conf
e no arquivo que abriu fiz as seguintes alteraçoes>
options snd-pcsp index=-2
options snd-hda-intel model=hp-dv5
nao e como antes que estava no model hp-dv6

Citar
no termina e fui para este outro arquivo: sudo gedit /boot/grub/menu.lst
e la editei o seguinte inseri pci=noacpi nesta linha do kernel

title Ubuntu 9.04, kernel 2.6.28-15-generic

initrd /boot/initrd.img-2.6.28-15-generic
quiet
agradeco a todos pelas dicas esta quase 100% agora
Obs: fiz a atulizacao para a versa ubuntu 9.10
