In order to support a unique output API which is version independent, it is recommended to install and use the AudioTools library. Unfortunately Espressif has decided to go for a completely new I2S API which means that my integration needs to be rewritten. I haven't tried to make it work at higher rates (it's possible, though, as per the datasheet), but from my experience with another I2S driver (for H3 processor), it's a matter of choosing the right system clock. Yohannfra/esp32-wav-player-i2s. Either I added too many libraries which use the same libraries (I get "more than one blabla. Rob. Skip to content. Espressif ESP32 Official Forum. ESP32 has a dedicated DMA controller that could stream sample data without being dependent on the CPU to copy and It is not that the library has been downgraded, the message shows that you had very old version of ESP32-Arduino package installed (1. Channel select line. The SmartMatrix Library ESP32 port at a low level is based on Sprite_TM's ESP32 I2S Parallel example. Although the new I2S library will support so many channels of sound I do not know if the SD card will keep up.
