When i run xmms from the console i get the follow error:
root@knoppixbox:~# xmms

mpg321 plays the mp3 file without problems but xmms and audacity still sending an error
the xmms error says:
please check that
your soundcard is configured properly
you have the correct output plugin selected
no other program is blocking the soundcard

kde plays a sound when begins and y had tried all the output plugins
