With jack1 I was still having problems. Also occasionally the known
alignment-trap issue. I now built jack2 from latest git and it works!
(with your suggested 'jackd -d alsa -o 2 -i 2 -S -C hw:0,1 -P hw:0,0' to
specify the devices)
Also built vanilla Puredata with build-optimizations for pandora (and
enabled jack and disabled direct alsa) and this now works as well!
