If you want to investigate the problem not with basis in my minimal example code, but rather with basis in the demo file MultipleSources.java, then you the crash occurs if you replace the line al.alGenSources(NUM_SOURCES, sources); with these lines that create the sources one by one: int[] source0 = new int[1]; int[] source1 = new int[1]; int[] source2 = new int[1]; // not the same order as they will be deleted in: al.alGenSources(1, source0); al.alGenSources(1, source2); al.alGenSources(1, source1); sources = new int[] {source0[0],source1[0],source2[0]}; Is there anything I can do to be able to dynamically create and delete sources then?

Java Game APIs & Engines / Java Sound & OpenAL / Crash on alDeleteSources

on: 2004-09-25 23:25:24

Hi, I'm having a problem with Joal. The code below crashes Java when I run it. If I change it, so that the sources are deleted in the same order as they are created then there are no problems, but when I delete the sources in a different order than they were created in, then an Java crashes with the error "java.exe has encountered a problem and needs to close. We are sorry for the inconvenience.". Is there anything I can do? Since my system is to be dynamic, I need to be able to delete sources at any point in time, and thus not just in the order they were created...

4	Java Game APIs & Engines / Java Sound & OpenAL / Output to wav file rather than speakers?	on: 2004-09-15 14:05:42
Hi, I finally got JOAL working and I'm playing a bit with it now. I'd like to use JOAL to create the sound for a 3d animation I'm creating. It's a prerendered animation, not a real-time one, so I need the stereo sound generated by JOAL to be saved in a wav file rather than being played back immediately. Is that possible? Although I've gotten JOAL to play back sound effects the way I want it to, I'm still not very competent in its inner workings, so a simple explanation is preferred, perhaps even with example code, but I understand if it's too much to ask for. Anyway, I'm really excited about the things that JOAL offer (the dobbler effect is impressive in particular) so I really hope there's a solution. Best regards, Rune

Quote I've tried this link http://ftp://opensource.creative.com/pub/sdk/OpenALSDK.exe but the only file in http://ftp://opensource.creative.com/pub/sdk/ is OpenAL_Installer_10_1.bin Because I have the "null-Device" problem, I need a new and right OpenALSDK.exe I think. Where can I get it? I too am having this problem and i too would like to know where I can obtain the needed file. Thanks in advance, Rune
