Crash after I2S fix

[ahammers]

I am trying to get this project working on a LOLIN D32 with an ILI9341 display and a MAX98357A I2S DAC.

I had it working without sound for some time but since I changed the settings from direct DAC to I2S it stops working whenever I start a ROM.

in video_audio.c I disabled the build in DAC

		.mode = I2S_MODE_MASTER | I2S_MODE_TX,
//		.mode = I2S_MODE_MASTER | I2S_MODE_TX | I2S_MODE_DAC_BUILT_IN,

an I added the pin configuration to what I am using in my other projects:

static const i2s_pin_config_t pin_config = {
	.bck_io_num = 27,
	.ws_io_num = 26,
	.data_out_num = 25,
	.data_in_num = 0 // I2S_PIN_NO_CHANGE
};	
i2s_set_pin(I2S_DEVICE_ID, &pin_config);

I don't hear any sound in the menu (don't know if this is normal) but when I start some ROM it get this messages and the system freezes (no display updates, menu button not working, ...):

Also I can't get the micro sd card reader to work with this project. It works in a stand alone project without changing the connections, but with nesemu it does not. But as long as I can use the SPIFFS this is no big deal for me.

Any ideas what I did wrong with the I2S configuration ?

UPDATE: I thought it's just a brownout because of the MAX98357 consuming too much power from the LOLIN D32 but even with the I2S DAC removed it hangs after "Timer install 60 Hz". But if I change i2s_set_pin(I2S_DEVICE_ID, &pin_config); back to i2s_set_pin(I2S_DEVICE_ID, NULL); it works without sound (but I can play Super Mario)
