[7a8c3f28] | 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>
|

| 17 |
|
---|
| 18 | <para>The alsa-drivers package installs a script as
|
---|
| 19 | <filename>/etc/rc.d/init.d/alsasound</filename>. While it is possible to use
|
---|
| 20 | this script, it contains a lot of extraneous detail which isn't needed on an
|
---|
| 21 | LFS system and so we create our own script
|
---|
| 22 | <filename>/etc/rc.d/init.d/alsa</filename>.</para>
|
---|
| 23 |
|
---|
| 24 | <para>To create the alsa script, do the following:</para>
|
---|
| 25 |
|
---|
| 26 | <para><screen><userinput>cat > /etc/rc.d/init.d/alsa << "EOF"</userinput>

| 70 | <para>You can then create the appropriate symlinks:

| 71 | <screen><userinput>cd /etc/rc.d/init.d &&
|
---|
| 72 | ln -sf ../init.d/alsa ../rc0.d/K35alsa &&

|
---|
| 79 |
|
---|
| 80 | <para>Note that all channels of your soundcard are muted by default. You can
|
---|
| 81 | use the <filename>alsamixer</filename> program from alsa-utils (or any other
|
---|
| 82 | OSS mixer) to change this.</para>
|
---|
| 83 |
|
---|
| 84 | <para>Also, the first time the above script is run, it will complain that
|
---|
| 85 | there is no state in <filename>/etc/asound.state</filename>. You can
|
---|
| 86 | prevent this by running the following commands after installing alsa-utils:
|
---|
| 87 | <screen><userinput>touch /etc/asound.state &&
|
---|
| 88 | alsactl store</userinput></screen></para>
|
---|
| 89 |
|
---|
| 90 | <para>A final note is that the lines loading <filename>sfxload</filename>
|
---|
| 91 | are commented out. They are there as an example of other things you may
|
---|
| 92 | wish to do in the startup script. <filename>sfxload</filename> is a
|
---|
[5628618e] | 93 | separate package of interest to SoundBlaster AWE and Live! users. It is
|
---|
[7a8c3f28] | 94 | designed for loading "sound-fonts" (which are used for MIDI output). You
|
---|
| 95 | may wish to delete these lines and add your own or, if you have the relevant
|
---|
| 96 | soundcard, install <filename>sfxload</filename> and uncomment them.</para>
