Where can I find a working example of DAC use with ESP32-S2 (not using ESP8266Audio)? I tried to add support, but i2s_driver_install returns error. ``` AudioOutputI2S::begin... ... i2s_mode_t mode =...

It seems ESP32-S2 has no DAC mode using I2S

Also remark following change in ESP32-audioI2S which might inspire to detect the end of the stream https://github.com/schreibfaul1/ESP32-audioI2S/commit/ed13136ebe0b5da6d8377912596c6e0fce5ba96d#diff-6033949d768051c96b2a380edec84a3e1cbe58b3a94e41aae408c6a8f8bbc2b2

The default pin for NoDAC on ESP32 is pin 22. Sound quality is really good with the standard oversampling 32. And even better with oversampling 64.

I2S implementation for ESP32 worked well until version 2.0.0rc2. But in that version I2S for ESP32C3 didn´t work. In 2.0.1 i2s doesn´t work on ESP32 but works for ESP32C3

- Use ESP core version 1.0.6 or 2.0.0rc2 - Use the latest version of ESP8266Audio Do not confuse internal DAC with NoDac, which is something different. Internal DAC - internal...

NoDac works on Esp32, it is by default on pin 22

Would be cool to use it with https://github.com/Aircoookie/WLED

To get sound out of ESP32-S2 - I2S-DAC doesn't work because of hardware limitations (I2S cannot go directly to DAC) - ULP doesn't work because IDF doesn't support ULP-FSM yet...

This issue can be closed as the bug is fixed: internal DAC on ESP32 is working in ESP8266Audio version >=1.9.7 and IDF 4.4.1 (arduino core 2.0.3) or IDF 4.4.2 (Arduino...
