Dear list,
it seems that pd can only connect to jack when started without a -noadc flag, ie.
pd -noprefs -jack -noadc
does not work, while
pd -noprefs -jack
does work. This is Pd-0.43.1 ("test5") compiled 19:10:13 Dec 12 2011, a vanilla git checkout. Jack is jackd2 on Debian, version 1.9.8~dfsg.4+20120529git007cdc37-4.1
No big problem, but puzzling to anyone wondering why jack has stopped working.
best, Peter
