I've tried other parameters before to no avail. I did notice this post on the alsa list: http://www.mail-archive.com/alsa-user@xxxxxxxxxxxxxxxxxxxxx/msg11011.html and thought that maybe others had encountered this problem as well. Can someone tell me what my limitations are going to be if I can't run jack in duplex mode? Will I be able to user ardour on its own to do multitracking from the line-in/mic? Thanks!
