c - 无法同时播放两种声音

Question

有人能解释一下为什么我不能同时播放两个声音吗？

部分代码:

#include <fmod.h>

FMOD_SYSTEM *system;
FMOD_SOUND *dooropen;
FMOD_SOUND *keydoor;
FMOD_SOUND *slap;
FMOD_SOUND *bomb;
FMOD_SOUND *scratch;
FMOD_SOUND *secret;
FMOD_SOUND *pickey;
FMOD_SOUND *caisse;

FMOD_RESULT resultat1;
FMOD_RESULT resultat2;
FMOD_RESULT resultat3;
FMOD_RESULT resultat4;
FMOD_RESULT resultat5;
FMOD_RESULT resultat6;
FMOD_RESULT resultat7;
FMOD_RESULT resultat8;


FMOD_System_Create(&system);
FMOD_System_Init(system, 1, FMOD_INIT_NORMAL, NULL);


resultat1 = FMOD_System_CreateSound(system, "sound/door-open.mp3", FMOD_CREATESAMPLE, 0, &dooropen);

resultat2 = FMOD_System_CreateSound(system, "sound/key-door.wav", FMOD_CREATESAMPLE, 0, &keydoor);

resultat3 = FMOD_System_CreateSound(system, "sound/slap.wav", FMOD_CREATESAMPLE, 0, &slap);

resultat4 = FMOD_System_CreateSound(system, "sound/bomb.wav", FMOD_CREATESAMPLE, 0, &bomb);

resultat5 = FMOD_System_CreateSound(system, "sound/scratch.wav", FMOD_CREATESAMPLE, 0, &scratch);

resultat6 = FMOD_System_CreateSound(system, "sound/secret.wav", FMOD_CREATESAMPLE, 0, &secret);

resultat7 = FMOD_System_CreateSound(system, "sound/pickey.wav", FMOD_CREATESAMPLE, 0, &pickey);

resultat8 = FMOD_System_CreateSound(system, "sound/caisse.wav", FMOD_CREATESAMPLE, 0, &caisse);

我这样称呼我的声音:

FMOD_System_PlaySound(system, FMOD_CHANNEL_FREE, scratch, 0, NULL);
FMOD_System_PlaySound(system, FMOD_CHANNEL_FREE, bomb, 0, NULL);

我认为存在 channel 问题，因为当我播放“bomb”时我可以听到它(这个声音大约 3 秒)但是如果“scratch”声音发生，“bomb”声音就会停止...

FMOD_System_Init() 中的第二个参数是 maxchannels。只需将其设置为 2 或更高。在官方教程中他们使用 100。
