I think if more requested are sent we get more chance to have this feature
added.
I mailed Jaroslav Kysela (perex_at_suse.cz): I think he is the ICE1712
mantainer, but I am not sure, I didn't find direct infos on the web
regarding ICE1712 mantainer.

I think it can't be done like this: the problem is due to soundcard buffer,
which after some time goes empty and the system locks.
More I have the "clicks" problem, which wouldn't be solved running more jack
istances.

Hard problem...:-)
