(in English) the device or the ressource is possessed.
the above message means that the device (soundcard) is in use.
look for any applications that can be using the card.
for me it was usually a flash applet in a browser.
so to properly test this, close all those programs and try xmms by itself.
once you get your ALSA settings to be saved for each boot (i dont know how), you should set up some sort of mixing, that will enable more than one program to use the card at the same time.
