支持开始录音，停止录音，恢复，暂停录音，设置音量，增益，静音，选择场景等功能。

选择录音场景，媒体，蓝牙，通话：

static void SelectSceneMenu(void)
{
    printf(" ====================  Select Scene ==================== \n");
    printf("0 is Midea.                                             |\n");
    printf("1 is Communication.                                     |\n");
    printf("2 is Voice-all.                                         |\n");
    printf(" ======================================================= \n");
}

    int32_t val = 0;
    struct AudioSceneDescriptor captureScene;
    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) {
