Configuration Information
Use a bootscript to store the values at shutdown.
As the root user, install the init script /etc/rc.d/init.d/alsa included in the blfs-bootscripts package.
make install-alsa
Note that all channels of your sound card are muted by default. You can use the alsamixer program from the ALSA Utilities to change this.
The first time the alsactl program is run from the udev rule below, it will complain that there is no state in /etc/asound.state. You can prevent this by running the following commands as the root user:
touch /etc/asound.state && alsactl store
As the root user, install a new Udev rules file to create the audio device nodes and run the restore script:
cat > /etc/udev/rules.d/15-alsa.rules << "EOF" # Give the audio group ownership of sound devices SUBSYSTEM=="sound", GROUP="audio" SUBSYSTEM=="snd", GROUP="audio" # ALSA Devices # When a sound device is detected, restore the volume settings KERNEL=="controlC[0-9]*", ACTION=="add", RUN+="/usr/sbin/alsactl restore %n" KERNEL=="hw[CD0-9]*", NAME="snd/%k" KERNEL=="pcm[CD0-9cp]*", NAME="snd/%k" KERNEL=="midiC[D0-9]*", NAME="snd/%k" KERNEL=="timer", NAME="snd/%k" KERNEL=="seq", NAME="snd/%k" EOF chmod 644 /etc/udev/rules.d/15-alsa.rules
