Hear no sound from the four openal tests.

[Yukosu]

I tried to compile and run the four openal test projects(simgear/sound/openal_test1.cxx openal_test2.cxx openal_test3.cxx openal_test4.cxx), and heard no sound, but the sound system is working well in flightgear.

openal_test2.cxx:

Code: Select all

#include <stdio.h>
#ifdef _WIN32
#include <windows.h>
#define sleep(x) Sleep(x*1000)
#else
#include <unistd.h>
#endif

#include <simgear/debug/logstream.hxx>
#include <simgear/misc/sg_path.hxx>

#include "soundmgr_openal.hxx"
#include "sample_group.hxx"
#include "sample_openal.hxx"


int main( int argc, char *argv[] ) {
    SGSampleGroup *sgr;
    SGSoundMgr *smgr;

    smgr = new SGSoundMgr;

    smgr->bind();
    smgr->init();
    sgr = smgr->find("default", true);
    smgr->set_volume(0.9);
    smgr->activate();

    SGPath srcDir(SRC_DIR);

    SGSoundSample *sample1 = new SGSoundSample("jet.wav", srcDir);
    sample1->set_volume(1.0);
    sample1->set_pitch(1.0);
    sample1->play_looped();
    sgr->add(sample1, "sound1");
    smgr->update(1.0);
    printf("playing sample1\n");
    sleep(1);

    SGSoundSample *sample2 = new SGSoundSample("jet.wav", srcDir);
    sample2->set_volume(0.5);
    sample2->set_pitch(0.4);
    sample2->play_looped();
    sgr->add(sample2, "sound2");
    smgr->update(1.0);                // debugging shows it stucks here
    printf("playing sample2\n"); 
    sleep(1);

//  ...

    smgr->unbind();
    sleep(2);
    delete smgr;
}
   


Dunno what the problem is. Has anyone ever tried these tests?
I'm quite a newbie and hope someone could help. Thanks in advance.

From a quick look at the source: where did you define SRC_DIR?

Oh, maybe I missed a #define at the beginning. Anyway the project has no compiling errors.
