Recently I've added a second soundcard to my system , a SB Live! by Creative. ( module snd_emu10k1 )
I also have an onboard AC'97-compliant CK804 ( module snd_intel8×0 )

The problem is that ALSA does not see the second card at all:

tajwan:/etc/modprobe.d# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: CK804 [NVidia CK804], device 0: Intel ICH [NVidia CK804]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: CK804 [NVidia CK804], device 2: Intel ICH - IEC958 [NVidia CK804 - IEC958]
Subdevices: 1/1
Subdevice #0: subdevice #0

sees only the onboard card. Similarly,

tajwan:/etc/modprobe.d# cat /proc/asound/cards
0 [CK804 ]: NFORCE - NVidia CK804
NVidia CK804 with ALC850 at irq 22

sees only the CK804. But, the modules for my PCI card get loaded correctly:

here's my /etc/modprobe.d/sound:

tajwan:/etc/modprobe.d# cat /etc/modprobe.d/sound
alias snd-card-0 snd-intel8×0
options snd-intel8×0 index=0
alias snd-card-1 snd-emu10k1
options snd-emu10k1 index=1

I've also added a 'options snd cards_limit=2' to /etc/modprobe.d/alsa-base, as per advice from ALSA webpage. Didn't help.

What gives?? Anyone's got an idea??
