/etc/modules.conf and /etc/asound.state To configure the alsa drivers, you need to add some lines to /etc/modules.conf: cat >> /etc/modules.conf << "EOF" alias char-major-14 soundcore alias char-major-116 snd alias snd-card-0 snd-<soundcard-name> alias sound-slot-0 snd-card-0 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-midi EOF <soundcard-name> needs to be replaced with the driver relevant to your soundcard. If you have more than one soundcard, you can add additional sections by repeating the above but changing the first 0 to 1 and so on. After editing /etc/modules.conf you need to run depmod. If the drivers you have compiled are for the version of the kernel you are currently running, simply run depmod If you are compiling drivers for a different kernel version to that which you are running, you will need to use a line along the lines of: depmod -a 2.4.19 -F /boot/System.map-2.4.19 Probably the easiest way to store mixer levels is to set and retrieve them using a bootscript. It is possible to do this with a post-install line in /etc/modules.conf but this is left as an exercise for those readers who wish to do this. The alsa-drivers package installs a script as /etc/rc.d/init.d/alsasound. While it is possible to use this script, it contains a lot of extraneous detail which isn't needed on an LFS system and so we create our own script /etc/rc.d/init.d/alsa. To create the alsa script, do the following: cat > /etc/rc.d/init.d/alsa << "EOF" #!/bin/sh # Begin $rc_base/init.d/alsa # Based on sysklogd script from LFS-3.1 and earlier. # Rewritten by Gerard Beekmans - gerard@linuxfromscratch.org # ALSA specific parts by Mark Hymers - markh@linuxfromscratch.org # Stores mixer settings in the default location: /etc/asound.state source /etc/sysconfig/rc source $rc_functions case "$1" in start) echo -n "Starting alsa... Restoring volumes..." loadproc /usr/sbin/alsactl restore #echo -n " Loading MIDI font..." #loadproc sfxload /path/to/soundfont ;; stop) echo -n "Stopping alsa... Saving volumes......" loadproc /usr/sbin/alsactl store #echo -n " Removing MIDI font.........." #loadproc sfxload -i ;; restart) $0 stop /usr/bin/sleep 1 $0 start ;; *) echo "Usage: $0 {start|stop|restart}" exit 1 ;; esac # End $rc_base/init.d/alsa EOF chmod 755 /etc/rc.d/init.d/alsa You can then create the appropriate symlinks: cd /etc/rc.d/init.d && ln -sf ../init.d/alsa ../rc0.d/K35alsa && ln -sf ../init.d/alsa ../rc1.d/K35alsa && ln -sf ../init.d/alsa ../rc2.d/S40alsa && ln -sf ../init.d/alsa ../rc3.d/S40alsa && ln -sf ../init.d/alsa ../rc4.d/S40alsa && ln -sf ../init.d/alsa ../rc5.d/S40alsa && ln -sf ../init.d/alsa ../rc6.d/K35alsa Note that all channels of your soundcard are muted by default. You can use the alsamixer program from alsa-utils (or any other OSS mixer) to change this. Also, the first time the above script is run, it will complain that there is no state in /etc/asound.state. You can prevent this by running the following commands after installing alsa-utils: touch /etc/asound.state && alsactl store A final note is that the lines loading sfxload are commented out. They are there as an example of other things you may wish to do in the startup script. sfxload is a seperate package of interest to SoundBlaster AWE and Live! users. It is designed for loading "sound-fonts" (which are used for MIDI output). You may wish to delete these lines and add your own or, if you have the relevant soundcard, install sfxload and uncomment them.
