No idea. But this implies that you have very strange setup.

No, don't, that's wrong!

It's an odd situation.  I guess you didn't install the driver properly.
Otherwise you must have /dev/snd/control*, PCM, else.

How to install the alsa-driver externally depends on the distro.
I'd advise you to ask on a distro forum about it at first.
The rest debugging starts after you can install the sound drivers
properly.

thanks,

Takashi
