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...
