This article mainly explains "how to implement HP notebook Debian system compilation and installation of sound card driver", interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Next let the editor to take you to learn "how to achieve HP notebook Debian system compilation and installation of sound card driver" bar!

When you install Debian 5 when you first buy a Hewlett-Packard laptop, you usually encounter two problems:

One is that the wireless network card driver is not installed, and the other is that "you can listen to music with headphones, but the loudspeaker cannot make sound."

The second problem is mostly due to the low version number of the Debian 5 sound card driver, so as long as you download the latest sound card driver, the compilation and installation will solve the problem.

The steps are as follows:

1. Download the latest driver from the alsa home page and extract it to the current directory

Alsa-driver-1.0.21.tar.bz2

Alsa-lib-1.0.21a.tar.bz2

Alsa-utils-1.0.21.tar.bz2

$pwd

/ home/c-aries/download/alsa

$ls

Alsa-driver-1.0.21.tar.bz2 alsa-lib-1.0.21a.tar.bz2 alsa-utils-1.0.21.tar.bz2

$tar xf alsa-driver-1.0.21.tar.bz2

$tar xf alsa-utils-1.0.21.tar.bz2

$tar xf alsa-lib-1.0.21a.tar.bz2

$ls-F

Alsa-driver-1.0.21/ alsa-lib-1.0.21a/ alsa-utils-1.0.21/

Alsa-driver-1.0.21.tar.bz2 alsa-lib-1.0.21a.tar.bz2 alsa-utils-1.0.21.tar.bz2

$

two。 Install the necessary software packages and close the sound card

$sudo apt-get install build-essential ncurses-dev gettext xmlto linux-headers- `uname-r`libncursesw5-dev

$sudo / etc/init.d/alsa-utils stop

3. Function libraries related to soft links

Run the following command only when there is an error in compilation, such as reporting an error

Checking for new_panel in-lpanelw.. No

Configure: error: panelw library not found

Link command:

$sudo ln-s libpanelw.so.5 / usr/lib/libpanelw.so

$sudo ln-s libformw.so.5 / usr/lib/libformw.so

$sudo ln-s libmenuw.so.5 / usr/lib/libmenuw.so

$sudo ln-s libncursesw.so.5 / lib/libncursesw.so

4. Compile and install alsa-driver,alsa-lib,alsa-utils in turn

$pwd

/ home/c-aries/download/alsa/alsa-driver-1.0.21

$. / configure

$make

$sudo make install

$pwd

/ home/c-aries/download/alsa/alsa-lib-1.0.21a

$. / configure

$make

$sudo make install

# you need to compile alsa-driver and alsa-lib before you can compile alsa-utils, otherwise you will get an error when you run configure

$pwd

/ home/c-aries/download/alsa/alsa-utils-1.0.21

$. / configure

$make

$sudo make install

5. Restart the system to check the sound card driver version number

$cat / proc/asound/version

Advanced Linux Sound Architecture Driver Version 1.0.21.

Compiled on Dec 9 2009 for kernel 2.6.26-2-686 (SMP).

$

6. Configure sound card and adjust volume

# close the sound card

$sudo / etc/init.d/alsa-utils stop

# configure sound card, select sound card for configuration, and select hda-intel

$sudo alsaconf

# adjust the volume, set both Master and PCM to 100. the sound of the external speaker is very loud.

# Tip: press m key, for example, the OO flag appears under Master, indicating that this option can be used; press m key again, such as the MM flag appears under Master, indicating that this option is disabled

$alsamixer
