Hi Jaroslav!
here we go:
I added some printk's to these routines:

for (idx = 0; idx < kcontrol->count; idx++, id.index++, id.numid++)
snd_ctl_notify(card, SNDRV_CTL_EVENT_MASK_ADD, &id);

----------------------------------------------------------------------

this is my syslog-output:
what bugs me is that the very first syslog message is crippled.
are there any problems with gcc 3.2.3 ?! (or with glibc 2.3.2)

--------------------------------------------------------------------------------
I did in the meanwhile another test with the latest 4F-OSS stuff
(ftp://www.se.opensound.com/pub/oss/linux/oss398b-linux-v2x.tar.gz).
They're having the same problem with the interwave card (error message
is almost the
same which says that the card is not found or busy...).
Did they copy the alsa-engine and are now charging money for it ?
