According to

http://www.rme-audio.com/english/linux/alsa.htm

Hammerfall is supported in Alsa. Odd.

I'd not be surprised if sndconfig (which is for pretty much obsolescent soundcards) couldn't handle it.

If we're talking (as I'm begining to suspect) about a Hard Drive install, you should run

alsa_init

But, in the meantime, please do post your lspci -v output.
