Thanks Clemens

So for capture I do jackstart Rv -d alsa -C hw:0,1 ,and indeed 
jack starts ,and with -P hw:0,0 it starts too.I got it.

But then the troubles begin.
When I try jackstart -d alsa -P hw:0,0 -C hw:0,0,the system
freezes with kernel panic.
If jack is running with -P hw:0,0 ,and try to play sound
with alsaplayer -o jack *.ogg,I get a similar crash.
And when I'm run jack with -C hw:0,1 and then open ardour 
after some clicks the system freezes too. 

Should I give up jack for this card?Or am I missing something
or is it a bug.And if yes,will it be fixed?

When I try alsaplayer without jack,it uses oss but there is 
sound.
But maybe there is some tuning needed for making the 
4 channel device work? Or am I wrong?

Ciao,
