After a bit of research i was able to fix the problem. Maybe someone is facing a similar issue. The clue was to set the communication_format to I2S_COMM_FORMAT_I2S in the i2s config struct: i2s_config_t i2s_config = { .mode = I2S_MODE_MASTER | I2S_MODE_TX, // Only TX .sample_rate = 44100, .bits_per_...
