I hope this isn't considered a cross-post, as I've already posted something similar to freebob-dev. But I think I may be beyond compile/install issues and on to basic user issues. I've managed to get freebob enabled jackd to build and run on my system, Ubunto Dapper 64bit version. I can run the daemon, but can't seem to get any jack clients to connect to it. When I run jackd, I see this EXCITING output: sudo jackd -v -R -P70 -dfreebob -r48000 -p512 -n2 getting driver descriptor from /usr/local/lib64/jack/jack_alsa.so getting driver descriptor from /usr/local/lib64/jack/jack_dummy.so getting driver descriptor from /usr/local/lib64/jack/jack_oss.so getting driver descriptor from /usr/local/lib64/jack/jack_freebob.so jackd 0.102.20 Copyright 2001-2005 Paul Davis 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 JACK compiled with System V SHM support. server `default' registered loading driver .. registered builtin port type 32 bit float mono audio registered builtin port type 8 bit raw midi clock source = system clock via gettimeofday new client: freebob_pcm, id = 1 type 1 @ 0x5290e0 fd = -1 Freebob using Firewire port 0, node -1 new buffer size 512 showDevice: not implemented FreeBoB MSG: Streaming thread running with Realtime scheduling, priority 74 FreeBoB MSG: Registering capture port dev1c_SpdifIn L FreeBoB MSG: Registering capture port dev1c_SpdifIn R FreeBoB MSG: Registering capture port dev1c_LineIn L FreeBoB MSG: Registering capture port dev1c_LineIn R FreeBoB MSG: Registering playback port dev1p_SpdifOut L FreeBoB MSG: Registering playback port dev1p_SpdifOut R FreeBoB MSG: Registering playback port dev1p_LineOut L FreeBoB MSG: Registering playback port dev1p_LineOut R FreeBoB MSG: MIDI threads running with Realtime scheduling, priority 73 registered port freebob_pcm:dev1c_SpdifIn L, offset = 2048 registered port freebob_pcm:dev1c_SpdifIn R, offset = 4096 registered port freebob_pcm:dev1c_LineIn L, offset = 6144 registered port freebob_pcm:dev1c_LineIn R, offset = 8192 registered port freebob_pcm:dev1p_SpdifOut L, offset = 0 registered port freebob_pcm:dev1p_SpdifOut R, offset = 0 registered port freebob_pcm:dev1p_LineOut L, offset = 0 registered port freebob_pcm:dev1p_LineOut R, offset = 0 ++ jack_rechain_graph(): client freebob_pcm: internal client, execution_order=0. -- jack_rechain_graph() FreeBoB MSG: MIDI queue thread started libiec61883 warning: Established connection on channel 0.
