From MEPIS Documentation Wiki
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.
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
- aseqdump: command line MIDI sequencer control
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:
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:
