It sure does work. I've had problems in the past with some distros where my card (Delta 1010LT)
hasn't been initialized at boot, in which case the card is not recognized. But if it is, then envy24control controls your card nicely.
Alternatively you can use 'mudita24control' by this list's Jörn Nettingsmeier.
Gives you nicer GUI with db readouts.
