<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">

<para>As the root user, install the init script

<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 &&

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>
