Configuring Audio Devices

Making audio devices work in Linux can be complex and frustrating. Here are some tips:

Login to the console from another computer.

Use this command to list the audio devices that the system knows about:

aplay -l

Also you can try this command for more details:

aplay -L

alsamixer is a Linux command that allows you to set levels for devices and graphically display settings. You just type:

alsamixer

followed by the Enter key in the terminal/console.
