<title>Installation of <application><acronym>ALSA</acronym> 
Utilities</application></title>

<para>Install <application><acronym>ALSA</acronym> Utilities</application> by 
running the following commands:</para>

<screen><userinput><command>./configure &amp;&amp;
make</command></userinput></screen>

<para>Now, as the root user:</para>

<screen><userinput role='root'><command>make install</command></userinput></screen>

<title>Configuring <application><acronym>ALSA</acronym> 
Utilities</application></title>

<para><filename>/etc/asound.state</filename></para>
<indexterm zone="alsa-utils alsa-utils-config">
<primary sortas="e-etc-asound.state">/etc/asound.state</primary></indexterm>
</sect3>

<sect3 id="alsa-utils-init"><title>Configuration Information</title>
<para>Probably the easiest way to store mixer levels is to set and retrieve
them using a bootscript.</para>
<indexterm zone="alsa-utils alsa-utils-init">
<primary sortas="f-alsa">alsa</primary></indexterm>

<para>As the root user, install the init script 
<filename>/etc/rc.d/init.d/alsa</filename> included in the 
<xref linkend="intro-important-bootscripts"/> package.</para>

<screen><userinput role='root'><command>make install-alsa</command></userinput></screen>

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

<para>The first time the above script is run, it will complain that
there is no state in <filename>/etc/asound.state</filename>.  You can
prevent this by running the following commands as the root user after 
installing <application><acronym>ALSA</acronym> Utilities</application>:</para>

<screen><userinput role='root'><command>touch /etc/asound.state &amp;&amp;
alsactl store</command></userinput></screen>

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