Install ALSA Utilities by running the following commands:
./configure && make
This package does not come with a test suite.
Now, as the root user:
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-20060910 package.
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. Use speaker-test to check that your settings have been applied correctly.
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
The volume settings will be restored from the saved state by Udev when the device is detected (during boot or when plugged in for USB devices).
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/40-alsa.rules << "EOF" # /etc/udev/rules.d/40-alsa.rules # When a sound device is detected, restore the volume settings KERNEL=="controlC[0-9]*", ACTION=="add", RUN+="/usr/sbin/alsactl restore %n" EOF chmod -v 644 /etc/udev/rules.d/40-alsa.rules
