|

74 | <para>Probably the easiest way to store mixer levels is to set and retrieve
|
---|
75 | them using a bootscript. It is possible to do this with a
|
---|
76 | <userinput>post-install</userinput> line in
|
---|
77 | <filename>/etc/modules.conf</filename> but this is left as an exercise for
|
---|
78 | those readers who wish to do this.</para>
|
---|
79 |
|
---|
80 | <para>The <application><acronym>ALSA</acronym> Driver</application> package
|
---|
81 | installs a script as <filename>/etc/rc.d/init.d/alsasound</filename>. While it
|
---|
82 | is possible to use this script, it contains a lot of extraneous detail which
|
---|
83 | isn't needed on an <acronym>LFS</acronym> system. Instead, install the init
|
---|
84 | script <filename>/etc/rc.d/init.d/alsa</filename> included in the
|
---|
85 | <xref linkend="intro-important-bootscripts"/> package.</para>
|
---|
86 |
|
---|
87 | <screen><userinput><command>make install-alsa</command></userinput></screen>
|
---|
88 |
|
---|
89 | <para>Note that all channels of your sound card are muted by default. You can
|
---|
90 | use the <command>alsamixer</command> program from
|
---|
91 | <application><acronym>ALSA</acronym> Utilities</application> (or any other
|
---|
92 | <acronym>OSS</acronym> mixer) to change this.</para>
|
---|
93 |
|
---|
94 | <para>The first time the above script is run, it will complain that
|
---|
95 | there is no state in <filename>/etc/asound.state</filename>. You can
|
---|
96 | prevent this by running the following commands after installing
|
---|
97 | <application><acronym>ALSA</acronym> Utilities</application>:</para>
|
---|
98 | <screen><userinput><command>touch /etc/asound.state &&
|
---|
99 | alsactl store</command></userinput></screen>

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