[Alsa-user] Can't modprobe soundblaster 16

[Jens N. <nac...@we...>]

I have a creative soundblaster 16. When I do a:
modprobe snd-sb16 snd_port=0x220 snd_mpu_port=0x330 snd_irq=5 snd_dma8=3 snd_dma16=7

I get:
/lib/modules/2.4.20/alsa/snd-sb16.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters
/lib/modules/2.4.20/alsa/snd-sb16.o: insmod /lib/modules/2.4.20/alsa/snd-sb16.o failed
/lib/modules/2.4.20/alsa/snd-sb16.o: insmod snd-sb16 failed

I am sure about the port and the mpu_port, because I manually
set it to this with jumpers. I am also pretty sure about the irq and
dma8 and dma16, because I wrote it down from my old windows98 
installation.

Do you have any idea how I could trace my mistake? I already played 
with sndconfig and pnpdump without any results, and I am also insecure 
if that was the right direction

Thank you in advance,
Jens
