  如题，按照simple_adec_bind_ao.c和simple_ai_bind_aenc.c文件中的函数，写了录音和播放音频的逻辑。我希望能同时录音和播放音频。但是初始化的时候报错了，报错内容如下。

  Code: Select all

  是否输入和输出不能用同一个u8CardName？还是不能用相同的dev_id和chn_id? 我现在根据audio.c文件中的定义，是这么赋值的

  Code: Select all

  static int ai_dev_id = 0;
  static int ai_chn_id = 0;
  static int aenc_dev_id = 0;
  static int aenc_chn_id = 0;
  static int ao_dev_id = 0;
  static int ao_chn_id = 0;
  static int adec_dev_id = 0;
  static int adec_chn_id = 0;
  

  如果不对的话，该怎么初始化呢？
