选择菜单：

static void PrintMenu2(void)
{
    printf(" ================== Play Render Menu ================== \n");
    printf("| 1. Render Start                                      |\n");

支持开始播放，停止，恢复，暂停，设置音量，增益，静音，选择场景等功能。

选择播放场景：

static int32_t SelectRenderScene(struct IAudioRender **render)
{
    (void)render;

    int32_t val = 0;
    struct AudioSceneDescriptor scene;
    system("clear");
    SelectSceneMenu();
    printf("Please input your choice:\n");

    int32_t ret = CheckInputName(INPUT_INT, (void *)&val);
    if (ret < 0) {
        AUDIO_FUNC_LOGE("Invalid value!");
        SystemInputFail();
        return HDF_FAILURE;
    }

    switch (val) {
        case AUDIO_IN_MEDIA:
            scene.scene.id = AUDIO_IN_MEDIA;
            PrintRenderSelectPinFirst(&scene);
            break;
        case AUDIO_IN_COMMUNICATION:
            scene.scene.id = AUDIO_IN_COMMUNICATION;
            PrintRenderSelectPinSecond(&scene);
            break;
        case AUDIO_IN_RINGTONE:
            scene.scene.id = AUDIO_IN_RINGTONE;
            scene.desc.pins = PIN_OUT_SPEAKER | PIN_OUT_HEADSET;
            break;
        case AUDIO_IN_CALL:
            scene.scene.id = AUDIO_IN_CALL;
            PrintRenderSelectPinThird(&scene);
            break;
        case AUDIO_MMAP_NOIRQ:
            scene.scene.id = AUDIO_MMAP_NOIRQ;
            PrintRenderSelectPinFirst(&scene);
            break;
        default:
            break;
    }

    scene.desc.desc = "mic";

    if (g_render == NULL || g_render->SelectScene == NULL) {
        AUDIO_FUNC_LOGE("Music already stop,");
        SystemInputFail();
        return HDF_FAILURE;
    }

    ret = g_render->SelectScene((void *)g_render, &scene);
    if (ret < 0) {
        AUDIO_FUNC_LOGE("Select scene fail\n");
    }
    return ret;
}
