If needed, enable the following options in the kernel configuration and recompile the kernel:
Device Drivers --->
<*/M> Sound card support ---> [CONFIG_SOUND]
<*/M> Advanced Linux Sound Architecture ---> [CONFIG_SND]
Select settings and drivers appropriate for your hardware.In the Device Drivers ⇒ Sound card support ⇒ Advanced Linux Sound Architecture section of the kernel configuration, select the settings and drivers appropriate for your hardware. If necessary, recompile and install your new kernel.
Install ALSA Library by running the following commands:
./configure && make
If you have Doxygen installed and you wish to build the library API documentation, run the following commands from the top-level directory of the source tree:
make doc
To test the results, issue: make check.
Now, as the root user:
make install
To install the API documentation, run the following command as the
root user:
install -v -d -m755 /usr/share/doc/alsa-lib-1.2.7.2/html/search &&
install -v -m644 doc/doxygen/html/*.* \
/usr/share/doc/alsa-lib-1.2.7.2/html &&
install -v -m644 doc/doxygen/html/search/* \
/usr/share/doc/alsa-lib-1.2.7.2/html/search
The default alsa.conf is adequate
for most installations. For extra functionality and/or advanced
control of your sound device, you may need to create additional
configuration files. For information on the available
configuration parameters, visit https://www.alsa-project.org/main/index.php/Asoundrc.
