Re: ALSA Hammerfall DSP driver

Hi,

my Multiface now works. I am not quite sure exactly what I did right,
but I suspect it is that I now load snd_hammerfall_mem at boot time. I
suspect some kind of faulty state is introduced if snd_hammerfall_mem
isn't loaded in the correct way. This is impossible to correct later by
unloading all the alsa modules and start over. Maybe it can be made a
little more fault tolerant.

By the way, thanks for the driver!
