Hello, has anyone used audio/csound6 recently on FreeBSD? It compiles just fine, but it creates bogus output, AFAICS. Here's an example, simplified from Chapter 1 of The CSound Book: http://www.csounds.com/chapter1/ $ cat e1.orc sr = 44100 kr = 4410 ksmps = 10 nchnls = 1 instr 101 a1 oscil 10000, 440, 1 out a1 endin $ cat e1.sco ; Function 1 uses the GEN10 subroutine to compute a sine wave f 1 0 4096 10 1 ;inst start duration i 101 0 3 Running "csound e1.orc e1.sco" on Linux would create a file "test.wav" with a 440 Hz tone that can be rendered with any program like mplayer, vlc, etc... It would also display a sine wave as text. On FreeBSD, csound just runs in an endless loop, and test.wav grows and grows. If I stop csound with Ctrl-C, and inspect test.wav with hd(1), there's a header, followed by 00-bytes; that's all. I can vary the output format, it doesn't matter: always 00 samples are being output in an endless loop: $ csound e1.orc e1.sco virtual_keyboard real time MIDI plugin for Csound 0dBFS level = 32768.0 Csound version 6.06 (double samples) Jun 29 2016 libsndfile-1.0.26 orchname: e1.orc Elapsed time at end of orchestra compile: real: 0.004s, CPU: 0.000s sorting score ... ... done Elapsed time at end of score sort: real: 0.004s, CPU: 0.000s --Csound version 6.06 (double samples) Jun 29 2016 graphics suppressed, ascii substituted 0dBFS level = 32768.0 orch now loaded audio buffered in 256 sample-frame blocks writing 512-byte blks of shorts to test.wav (WAV) SECTION 1: ^C csound command: Interrupt csoundPerform(): stopped. 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: 9.596s, CPU: 9.539s 256 512 sample blks of shorts written to test.wav (WAV) $ ls -l test.wav -rw-r--r-- 1 cpghost users 221763644 Jun 29 18:35 test.wav $ hd test.wav 00000000 52 49 46 46 34 d8 37 0d 57 41 56 45 66 6d 74 20 |RIFF4.7.WAVEfmt | 00000010 10 00 00 00 01 00 01 00 44 ac 00 00 88 58 01 00 |........D....X..| 00000020 02 00 10 00 64 61 74 61 10 d8 37 0d 00 00 00 00 |....data..7.....| 00000030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 0d37d830 Needless to say that this output file plays silent. So, there's something definitively broken in audio/csound6, because this happens ONLY on FreeBSD, not on Linux.

Any advice? Thanks, -cpghost. -- Cordula's Web. http://www.cordula.ws/
