It is quite easy, if all files are of same type: audio type is same, audio sample rate and bits are same. You can check example: https://github.com/espressif/esp-adf/blob/master/examples/get-started/play_mp3_control/main/play_mp3_control_example.c, after file play to end, auto read next file. If fil...

简单一点你可以扫描I2C总线，简单点就是从 0-7F的地址里面读取一个字节的东西看对端有没有回应
每个Codec对应的I2C都只有特定的地址

可以看下你的ADF的版本，最新的版本默认应该是可以编译过的在IDF5.1上面
你可以手动打开下面的选项
Component config --> FreeRTOS --> Kernel
configENABLE_BACKWARD_COMPATIABILITY

If you already have a used IDF version which is compatiable with current ADF(4.4-5.1).
You do not need to use the IDF project in ADF submodules, you can use the IDF you already has, it also works well.

to use 24bits you need set mclk_multiple to be 384 as notes of IDF
* @note Please set the mclk_multiple to I2S_MCLK_MULTIPLE_384 while using 24 bits data width
* Otherwise the sample rate might be imprecise since the bclk division is not a integer

Record use ADC is possible, but the quality is not guaranteed, you can take S2 for example, you need implement your own element to build up the whole pipeline You need get data in timer interrupt instead of use normal task https://www.toptal.com/embedded/esp32-audio-sampling https://docs.espressif.c...

通常除了硬件连接以外，软件上也是要配置的
8388通过i2c进行寄存器设定
可以重点关注下 ES8388_MASTERMODE 看设定设否正确

If you are using customized protocol. First you need decide which voice data format to trasmit, raw pcm data or encoded data aac etc. Then add a simple protocol header to avoid data parse wrong. If use encoded data, you need find decoder to decode it out then send the pcm data to codec to output. If...

Is this what you need ?

If you want to play record sound directly. Make sure the format for play and record i2s setting is same. Lyat mini use I2S 1 to record and i2s 0 to play, make sure the port setting is correct also. You can let both i2s use default setting and only change the port define for record and play to check ...
