No error message, yet no sound

If your mixer settings are turned down, you will hear no sound.

MEPIS attempts to preset the mixer controls, but in some cases this does not work.

To correct your settings, open Kmix (the speaker icon in the tray at the bottom right of the desktop). Then click on the Mixer button.

In the Output tab, make sure the Master volume (on the far left) is turned up. Also, make sure PCM is turned up (the control with the blue squiggly line above it. Also if there are little round buttons (green lights) above these slider controls, make sure they are on (lighted).

Of course, you should also make sure your speakers are plugged in and powered on.
