[alsa-devel] /proc/asound/* shows signs of life, but alsactl see's nothing

This is confusing to me
(with or without the imac9,1 patch
for the imac)
there is still entries in /proc/asound

lrwxrwxrwx 1 root root 5 Apr 15 22:49 NVidia -> card0
dr-xr-xr-x 7 root root 0 Apr 15 22:49 card0
-r--r--r-- 1 root root 0 Apr 15 22:49 cards
-r--r--r-- 1 root root 0 Apr 15 22:49 devices
-r--r--r-- 1 root root 0 Apr 15 22:49 hwdep
-r--r--r-- 1 root root 0 Apr 15 22:49 pcm
-r--r--r-- 1 root root 0 Apr 15 22:49 timers
-r--r--r-- 1 root root 0 Apr 15 22:49 version

but when I do:
sudo /usr/sbin/alsactl store
/usr/sbin/alsactl: save_state:1502: No soundcards found...

I this a software issue, or is this because the kernel is missing
something important in patch_realtek.c ?

I've moved different things around in patch_realtek.c
but still no speaker sound or headphone, not even
the sound during boot when the module is being loaded.

Also what is the best way to find PCI SSID?
under codec#0:(I have)
