Test project: Audio_SPDIF_ESP32_fail.zip

ESP8266:

pio run -e esp8266 -t upload
pio run -e esp8266 -t uploadfs

Result: LED is connected to RX,GND. LED light is (visually) stable, audio plays OK.

ESP32:

pio run -e esp32 -t upload
pio run -e esp32 -t uploadfs

Result: LED is connected to gpio27,GND. LED light is unstable, audio is not playing.

I have exact same problem, it is not a problem of i2s capabilities because this project is able to output audio: https://github.com/amedes/esp_a2dp_sink_spdif

Altho from bluetooth and i want to have it play from sd card

I had the same problem. In AudioOutputSPDIF.cpp I commented out the line "rtc_clk_apll_enable(1, 28, 8, 5, 0);" (near line 187). Now it works correctly.
