Could someone please post a sample of working (tested)
modprobe.conf for this?

I have been trying to make it work for days.
dmesg reports of a problem not getting parent for ControlC0.

if I check it looks like no sound card is found.

cat proc pci finds pci device VT8233/A/8235 in address 0xdf00 and irq 22

Is this problem known by anybody?

Please post on a newsgroup don't try to mail me! I try to avoid spamm and
it's also good to let others know the sollution too!
