Introduction to ALSA Utilities

The ALSA Utilities package contains various utilities which are useful for controlling your sound card.

Package information

ALSA Utilities dependencies

Installation of ALSA Utilities

Install ALSA Utilities by running the following commands:

./configure &&
make &&
make install

Configuring ALSA Utilities

Config files

/etc/asound.state

Configuration Information

Probably the easiest way to store mixer levels is to set and retrieve them using a bootscript.

Install the init script /etc/rc.d/init.d/alsa included in the blfs-bootscripts-6.0 package.

make install-alsa

Note that all channels of your sound card are muted by default. You can use the alsamixer program from ALSA Utilities (or any other OSS mixer) to change this.

The first time the above script is run, it will complain that there is no state in /etc/asound.state. You can prevent this by running the following commands after installing ALSA Utilities:

touch /etc/asound.state &&
alsactl store

A final note is that the lines loading sfxload are commented out. They are there as an example of other things you may wish to do in the startup script. sfxload is a separate package of interest to SoundBlaster AWE and Live! users. It is designed for loading "sound-fonts" (which are used for MIDI output). You may wish to delete these lines and add your own or, if you have the relevant sound card, install sfxload and uncomment them.
