# 参数获取

音频输出提供参数获取特性，该特性通过对外接口GetParam进行获取。

#### AUDIO_GET_AUDIOPLAY_PARAM

通过指定module为DATA_AUDIO，cmd为AUDIO_GET_AUDIOPLAY_PARAM，data传入AudioPlayParams类型数据，可获取音频播放参数。示例如下：

```
VmiDataType module = DATA_AUDIO;
VmiCmd cmd = AUDIO_GET_AUDIOPLAY_PARAM;
AudioPlayParams audioPlayParams;
uint8_t* param = &audioPlayParams;
GetParam(module, cmd, param, sizeof(AudioPlayParams));
```
