1. Sound configuration

Sound output in Calculate Linux is handled by the ALSA driver. When the system boots for the first time, Calculate Linux sets the volume level on all channels to 70%. However, in some cases there would still be no sound. To detect your sound card, run the alsaconf console tool.

After that, press OK to proceed to the dialog box, where you can select your sound card:

Highlight your sound card particulars and press OK. Confirm your choice in the subsequent dialog: the sound card settings will be saved.

To increase and decrease the volume levels, you can use the standard KDE, XFCE, Gnome, etc. sound mixer, as well as the alsamixer tool, in the console.

To check your speakers, you can use the speaker-test tool. If your sound is 5.1, enter:

speaker-test -Dplug:surround51 -c6
