Hi. I create a simple patch with a dac~ and a csoundapi~ and connect the left outlet/inlet. When I turn on Pd audio processing, Pd disappears and I see some messages (using the -stderr flag). I have both jackd and pd set up for realtime, and at pretty high priorities from the scripts I use to start them. My audio IRQ is higher than jack, which is higher than pd, which is higher than pd-gui. Pd works fine for other patches. I compiled Csound5.06 on Linux, once with a bunch of options and once with just csoundapi~, replacing the first one. Does this look like something for the Pd list? Csound is saying segmentation fault... My csd file is at http://www.badmuthahubbard.com/apitest.csd Below is my Pd output while loading the .csd first and then turning on audio. Btw, it doesn't crash if I just put the csoundapi~ and dac~ objects in and turn on audio; only when they are connected. Thanks. -Chuckk ----------------------------------------- csoundapi~ 1.01 A PD csound class using the Csound 5.06.2 API (c) V Lazzarini, 2005-2007 Localisation of messages is disabled, using default language. time resolution is 1000.000 ns /home/chuckk/apitest.csd /home/chuckk/apitest.csd 0dBFS level = 32768.0 Csound version 5.06 beta (float samples) Jul 18 2007 libsndfile-1.0.17 UnifiedCSD: /home/chuckk/apitest.csd STARTING FILE Creating orchestra Creating score orchname: /tmp/filex9OWtg.orc scorename: /tmp/filejlUP5v.sco orch compiler: 17 lines read instr 11 Elapsed time at end of orchestra compile: real: 0.002s, CPU: 0.000s sorting score ... ... done Elapsed time at end of score sort: real: 0.003s, CPU: 0.000s Csound version 5.06 beta (float samples) Jul 18 2007 displays suppressed 0dBFS level = 32768.0 orch now loaded audio buffered in 256 sample-frame blocks SECTION 1: Csound tidy up: Segmentation fault inactive allocs returned to freespace end of score. overall amps 0. 0. overall samples out of range 0 errors in performance Elapsed time at end of performance: real: 11.255s, CPU: 0.410s Removing temporary file /tmp/file6b2OHL.srt ...
