| 12 | <para>Probably the easiest way to store mixer levels is to set and retrieve
|
|---|
| 13 | them using a bootscript. It is possible to do this with a
|
|---|
| 14 | <userinput>post-install</userinput> line in
|
|---|
| 15 | <filename>/etc/modules.conf</filename> but this is left as an exercise for
|
|---|
| 16 | those readers who wish to do this.</para>

| 18 | <para>The <application><acronym>ALSA</acronym> Driver</application> package
|
|---|
| 19 | installs a script as <filename>/etc/rc.d/init.d/alsasound</filename>. While it
|
|---|
| 20 | is possible to use this script, it contains a lot of extraneous detail which
|
|---|
| 21 | isn't needed on an <acronym>LFS</acronym> system. Instead, install the init
|
|---|
| 22 | script <filename>/etc/rc.d/init.d/alsa</filename> included in the
|
|---|
| 23 | <xref linkend="intro-important-bootscripts"/> package.</para>

| 27 | <para>Note that all channels of your sound card are muted by default. You can
|
|---|
| 28 | use the <command>alsamixer</command> program from
|
|---|
| 29 | <application><acronym>ALSA</acronym> Utilities</application> (or any other
|

| 32 | <para>The first time the above script is run, it will complain that
|
|---|
| 33 | there is no state in <filename>/etc/asound.state</filename>. You can
|
|---|
| 34 | prevent this by running the following commands after installing
|
|---|
| 35 | <application><acronym>ALSA</acronym> Utilities</application>:</para>

| 39 | <para>A final note is that the lines loading <filename>sfxload</filename>
|
|---|
| 40 | are commented out. They are there as an example of other things you may
|
|---|
| 41 | wish to do in the startup script. <filename>sfxload</filename> is a
|
|---|
| 42 | separate package of interest to SoundBlaster AWE and Live!
|
|---|
| 43 | users. It is designed for loading "sound-fonts" (which are used for
|
|---|
| 44 | <acronym>MIDI</acronym> output). You may wish to delete these lines and add
|
|---|
| 45 | your own or, if you have the relevant sound card, install <filename>sfxload
|
|---|
| 46 | </filename> and uncomment them.</para>
