Ok. It does need to be listed as a card in /proc/asound/cards, just as a
webcam with built in mike (although not a soundcard as such) will have a card
entry and uses snd_usb_audio. So why isn't it there?
Does it need firmware loading? I know some M-audio keyboards do. My Evolution
keyboard doesn't, but someone with the same as yours will say.
Have you tried it in a different USB slot if you have spare ones? Not in a
hub as some USB things don't like hubs.
The only other thing I can think of is that both the sound card and the
keyboard are trying to grab card0 and the soundcard is winning, thus the
keyboard can't use it. Now I've seen this the other way round due to the USB
coming up early in the boot process and my keyboard grabbing card0 leaving no
place for the actual soundcard.
This is a very old problem, but may for some reason be happening in your case,
so I suggest putting some index options in /etc/modprobe.d/options, which
will at least confirm if that is the problem or not. See below.
options snd_hda_intel index=0
options snd_usb-audio index=1
Best to reboot and then see if /proc/asound/cards lists both.
If not I'm a bit perplexed.
