Introduction

Advanced Linux Sound Architecture (ALSA) provides audio and MIDI functionality to the Linux operating system. It is installed by default with MEPIS 7 and usually picks up and configures the sound card automatically.

alsa-utils

A collection of utilities that includes:

    • amixer: command line mixer
    • alsamixer: curses mixer
    • amidi: read from and write to ALSA RawMIDI ports
    • aplay, arecord: command line playback and recording
    • aplaymidi, arecordmidi: command line MIDI playback and recording
    • aconnect
    • aseqnet
    • aseqdump: command line MIDI sequencer control

alsaconf

From the man page: "Alsaconf is a simple shell script which tries to detect the sound cards on your system and writes a suitable configuration file for ALSA. It will try to guess what GNU/Linux distribution you're running, and will act accordingly to the standards of that distribution, if specific support is available."

Run this command as root:

alsaconf

It will detect and set up your sound card manually; best used on machines with a single sound card. If that solution does not work, then it may help to run the next command:

alsactl store
