Adding commands to shutdown and reboot

And a nice desktop it is.

The only thing that might explain what's happening is that you may have
installed an unnecessary new gui, that might be over-shadowing the default volume control.

You could start over with a noimage cheatcode to see if things behave differently now that
you know what to look for.

Or start over with a new LiveUSB, heaven forbid.

I didn't install any new GUIs, I only installed ALSAequal but that isn't the source of the problem because it did the same thing even when I didn't had any equalizer.
Also do you think it has to do with my card or driver that Im using like you saw in the screenshots? But i also don't think that is the case because i used the same flash disk i use
on the screenshots you saw earlier on my brothers laptop with a different card and the problem still persists. What it could be?

An alsaequal plugin is available via Synaptic, but not installed by default in Knoppix 7.4.

But just after running:

sudo apt-get update

I think the fresh install will solve this...
