Introduction to ALSA Utilities

The ALSA Utilities package contains the command line utilities for the ALSA project. This package can be compiled only with the installed ALSA driver and the ALSA C library.

Project Homepage: http://www.alsa-project.org/

Dependencies

Required

Optional

Non-Multilib

If you do not have xmlto add --disable-xmlto to the configure command. If building with systemd add --with-systemdsystemunitdir=/lib/systemd/system to the configure command.

Compile the package:

./configure &&
make

Install the package

make install

Multilib

This package does not provide any libraries so only one installation is needed.

64Bit

If you do not have xmlto add --disable-xmlto to the configure command. If building with systemd add --with-systemdsystemunitdir=/lib/systemd/system to the configure command.


Compile the package:

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

Install the package

make install

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

Note

All channels of your sound card are muted by default. You can use the alsamixer program from the ALSA Utilities to change this.

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
