 From XMMS you can choose your hardware (Prefs / alsa plugin / config)
 From MPLAYER you can only choose when using OSS
 From RHYTMBOX you can't choose.

If you don't want to (can't) disable the first card (my case because it 
is my webcam : usb_audio)

For the programs which use alsa with the "default" card, you can change 
it in the ~/asound.rc (or /etc/alsa.conf), example :

         pcm.!default {
         type hw
         card 1
         }

         ctl.!default {
         type hw
         card 1
         }

You can also try to modify /usr/share/alsa/alsa.conf, but I think it's 
more dangerous...

I've make the following change :
       defaults.ctl.card 0
     defaults.pcm.card 0
to
     defaults.ctl.card 1
     defaults.pcm.card 1

And all hw:0,0 to hw:1,0

It's work quite well...
I only kept a error in some soft (mplayer) about /dev/mixer ?

If someone have more explanation...
