carefully go through /usr/share/alsa/alsa.conf and change the card references but not the device references (might want to make a backup copy first)

like (i change to second card called Card1 from default Card0 as example)

Code:

defaults.ctl.card 1
defaults.pcm.card 1
defaults.pcm.device 0
defaults.pcm.subdevice -1
defaults.rawmidi.card 1
defaults.rawmidi.device 0
defaults.rawmidi.subdevice -1
defaults.hwdep.card 1
defaults.hwdep.device 0
defaults.timer.class 1
defaults.timer.sclass 0
defaults.timer.card 1
defaults.timer.device 0
defaults.timer.subdevice 0

look in dmesg to see what the card # you need is (first is 0 second is 1 third is 2)

also further down in the file where you find reference to hw:0,0
change those as well like:

Code:

pcm.dmix {
	@args [ SLAVE FORMAT RATE ]
	@args.SLAVE {
		type string
		default "hw:1,0"
	}
pcm.dsnoop {
	@args [ SLAVE FORMAT RATE ]
	@args.SLAVE {
		type string
		default "hw:1,0"
	}

i think that's all you need and it should work (might need to restart alsa ?)

still i can't change it.

i modified the files as you said. and
I didn't have alsamixer, and installed it, started to config (alsaconf) and then it gives error that there's no sound device.
def sound mixer is gnome-sound-mixer - something like this.
i tried uninstall it and, re-installed alsa... there's no change.. still alsa gives error. and def sound card didn't change.

i messed something..?
