ok thanks for the reply i finally made some progress and have jack support compiled in now. however i know have another problem. So i have jackd starting at boot
ps axw 4581 ? SLsl 0:00 /usr/bin/jackd -R -d net when i run gnuradio its forks its own instnace of jackd. david@ubuntu-server:~$ ./jacktest.py linux; GNU C++ version 4.4.3; Boost_104000; UHD_003.004.000-307-gb61f4ad6 Using Volk machine: avx_64 -- USRP-B100 clock control: 10 -- r_counter: 2 -- a_counter: 0 -- b_counter: 20 -- prescaler: 8 -- vco_divider: 5 -- chan_divider: 5 -- vco_rate: 1600.000000MHz -- chan_rate: 320.000000MHz -- out_rate: 64.000000MHz -- >>> gr_fir_ccc: using SSE len(audio_taps) = 317 >>> gr_fir_fff: using SSE jackd 0.118.0 Copyright 2001-2009 Paul Davis, Stephane Letz, Jack O'Quinn, Torben Hohn and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details no message buffer overruns JACK compiled with System V SHM support. loading driver ..

Is this how its supposed to work? where are the runtime config vars for the forked jackd process?
