然后尝试编译play_mp3_dac 编译出现错误：
i2s_stream.h中
I2S_MODE_DAC_BUILT_IN 这个宏定义 在自己本身的idf 或者是adf目录下的idf 的某个头文件 都是有定义的 定义的值是16 但是这里就是会包错误， 在自己原先的idf 的iis dac例程编译也没报这个错误error: 'I2S_MODE_DAC_BUILT_IN' undeclared
强行在i2s_stream.h中 将I2S_MODE_DAC_BUILT_IN直接写成16 编译没出问题 然后下载到开发板中
运行出现下图日志错误

1、上述问题产生的原因以及解决办法
2、 为什么本地已经有idf了 adf里面的子模块还需要下载idf 而且我看跟着官网例程走下来的话， 实际上adf用的idf 还是在原先的idf上 并没有将idf_path修改到adf内部子模块的idf啊 所以我在想上述的问题会不会是这个原因。。
刚入门这块 如果问题太过拙劣 请见谅啊
照理说， 这个play_mp3_dac 不依赖任何外部器件 编译下载应该是能运行的至少， 不知是否我配置有误， 我已经在menuconfig中 使能了psram 以及选择了esp32-s2的那个开发板
