如何在 iPhone 上使用 OpenAL 播放循环声音

// 创建 OpenAL 上下文
alcDevice *device = alcOpenDevice(NULL);
alcContext *context = alcCreateContext(device, NULL);
alcMakeContextCurrent(context);

// 生成源对象
ALuint source;
alGenSources(1, &source);

// 加载声音文件到缓冲区中
ALuint buffer;
alGenBuffers(1, &buffer);
// 将声音文件加载到缓冲区中
// ...

// 将缓冲区与源对象关联
alSourcei(source, AL_BUFFER, buffer);

// 播放源对象
alSourcePlay(source);

// 检查源对象的状态
ALint state;
alGetSourcei(source, AL_SOURCE_STATE, &state);
while (state == AL_PLAYING) {
    // 更新源对象的状态
    alGetSourcei(source, AL_SOURCE_STATE, &state);
}

// 释放源对象和缓冲区
alDeleteSources(1, &source);
alDeleteBuffers(1, &buffer);

// 释放 OpenAL 上下文和设备
alcMakeContextCurrent(NULL);
alcDestroyContext(context);
alcCloseDevice(device);
