Ubuntu 7.10正式版，alsa驱动的安装方法：
具体内容如下：
wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.15rc1.tar.bz2
tar xvpjf alsa-driver-1.0.15rc1.tar.bz2
cd alsa-driver-1.0.15rc1
./configure –with-cards=hda-intel,emu10k1
make
sudo make install
sudo gedit /lib/modules/2.6.22-14-generic/modules.dep
Replace the start of the line with hda-intel in it so that it starts with this:
/lib/modules/2.6.22-14-generic/kernel/sound/pci/hda/snd-hda-intel.ko
Remove the directory /lib/modules/2.6.22-14-generic/ubuntu/media/snd-hda-intel
Add the following line to /etc/modprobe.d/alsa-base：
options snd-hda-intel model=dell-3stack
重启即可。
