[zyshch]

sudo apt-get install build-essential ncurses-dev linux-headers-`uname -r`

sudo mkdir -p /usr/src/alsa
cd /usr/src/alsa
sudo cp //* ./
sudo tar xjf alsa-driver-1.0.19.tar.bz2
sudo tar xjf alsa-lib-1.0.19.tar.bz2
sudo tar xjf alsa-utils-1.0.19.tar.bz2



cd alsa-driver-1.0.19
sudo ./configure --with-cards=hda-intel
sudo make
sudo make install
sudo ./snddevices


cd ../alsa-lib-1.0.19
sudo ./configure
sudo make
sudo make install



cd ../alsa-utils-1.0.19
sudo ./configure
sudo make
sudo make install


配置文件
sudo gedit /etc/modprobe.d/sound

alias snd-card-0 snd-hda-intel
options snd-hda-intel model=laptop-automute
alias sound-slot-0 snd-hda-intel


options snd-hda-intel model=laptop-automute
options snd-hda-intel single_cmd=1 model=laptop-eapd
options snd-hda-intel model=laptop

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

options snd-hda-intel single_cmd=1 model=laptop-eapd
sudo gedit /etc/modprobe.d/options


alias snd-card-0 snd-hda-intel
options snd-hda-intel model=laptop
alias sound-slot-0 snd-hda-intel

[随风而誓]

illidan@illidan-laptop:~$ cd /usr/src/alsa
bash: cd: /usr/src/alsa: 没有该文件或目录
什么意思啊，我是新手，不太懂，照上面的代码复制过去显示这个
