CC="gcc ${BUILD64}" ./configure && make

Configuration Information
If using systemd, no configuration is needed and you can safely skip the rest of this page. Else, 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 bootscripts package.
make install-alsa
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]*", NAME="snd/%k", 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
udevtrigger /etc/udev/rules.d/15-alsa.rules
Using Newer udev, udevtrigger is removed from the install, use
udevadm trigger /etc/udev/rules.d/15-alsa.rules
- Note for users with multiple soundcards
Alsa tutorial for multiple soundcards
The first time the alsactl program is run from the udev rule above, 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
