I recently compiled csound on Kubuntu 7.10, and am still unable to get real-time audio playback. I have compiled csound also in the same manner on another partition in Ubuntu Studio, which works fine and I'm able to get realtime audio playback there. Here is what happens when I run csound: matt@waterStone:~/csound/ch1$ csound -odac 114.orc 114.sco Localisation of messages is disabled, using default language. time resolution is 1.000 ns PortAudio real-time audio module for Csound PortMIDI real time MIDI plugin for Csound 0dBFS level = 32768.0 Csound version 5.07 beta (float samples) Nov 22 2007 libsndfile-1.0.17 orchname: 114.orc scorename: 114.sco rtmidi: PortMIDI module enabled rtaudio: PortAudio module enabled ... using blocking interface orch compiler: 11 lines read instr 114 Elapsed time at end of orchestra compile: real: 0.059s, CPU: 0.000s sorting score ... ... done Elapsed time at end of score sort: real: 0.073s, CPU: 0.000s Csound version 5.07 beta (float samples) Nov 22 2007 graphics not supported on this terminal, ascii substituted 0dBFS level = 32768.0 orch now loaded audio buffered in 256 sample-frame blocks ;****see below (mk) PortAudio V19-devel PortAudio: available output devices: 0: HDA Intel: STAC92xx Digital (hw:0,1) 1: surround71 2: iec958 3: spdif 4: default 5: dmix Csound tidy up: Segmentation fault inactive allocs returned to freespace end of score. overall amps: 0.0 overall samples out of range: 0 0 errors in performance Elapsed time at end of performance: real: 13.558s, CPU: 0.550s Removing temporary file /tmp/fileZved88.srt ... At the line I have marked, csound hangs for about 10 seconds, then the rest of the feedback is displayed. Anyone help me diagnose this problem and fix it? Matt Kocubinski
