You need the realtime-lsm module.

Thanks Lee. That's at least got part of the problem out of the way and the
qjackctl output is shorter this time, but I still can't get jack to accept
connections. What I get now is:
20:30:39.141 Statistics reset.
20:30:39.369 Startup script...
20:30:39.370 killall artsd

Just so you know, I did modprobe realtime any=1 if that makes any difference,
because I don't know any better yet.
What am I still doing wrong?
Would the mysterious jackstart help me? I have read about this program but I
couldn't find a copy with my installation of jack, not even after I went to
jackit.sourceforge.net and rolled myself the official version, and therefore
I have no idea if it is important or not, or whether just doing killall
artsd ; jackd -d alsa -d whatnot is good enough.
Would messing about with the jackd command line arguments help me? I am
reluctant to do this because I don't know a lot about the architecture of my
card.
Many thanks
Robert
