hi,

there's some problem which I tracked down to

~alsa-driver/sound/core/control.c

int snd_ctl_add(snd_card_t * card, snd_kcontrol_t * kcontrol)
{
        snd_ctl_elem_id_t id;
        unsigned int idx;

    snd_runtime_check(card != NULL && kcontrol != NULL, return -EINVAL);
        snd_assert(kcontrol->info != NULL, return -EINVAL);
        id = kcontrol->id;
        down_write(&card->controls_rwsem);
    if (_ctl_find_id(card, &id)) {
                up_write(&card->controls_rwsem);
                snd_ctl_free_one(kcontrol);
                return -EBUSY;
    }
[...]

the problem lies in _ctl_find_id (card, &id). by commenting the if-block 
out, everything (as well
as the sound-card) works perfectly (as far as I could test it...).

this is the error-message I get when I leave eveything as it is:
----------------------------------------
root@sipiyou :/tmp/alsa/alsa-driver> modprobe snd-interwave
/lib/modules/2.4.22/kernel/sound/isa/gus/snd-interwave.o: init_module: 
No such device
Hint: insmod errors can be caused by incorrect module parameters, 
including invalid IO or IRQ parameters
/lib/modules/2.4.22/kernel/sound/isa/gus/snd-interwave.o: insmod 
/lib/modules/2.4.22/kernel/sound/isa/gus/snd-interwave.o failed
/lib/modules/2.4.22/kernel/sound/isa/gus/snd-interwave.o: insmod 
snd-interwave failed
----------------------------------------
/etc/modules.conf:
options snd-interwave index=0 id="GusPnP" enable=1 port=0x220 irq=11 
dma1=5 dma2=7

this is my config:
- devfs
- kernel 2.4.22
- amd interwave (ultrasound pnp)
