Error on startup of audio kit

[livingrainman]

After encountering the es8388 codec failure message on startup, I changed the I2C configuration in the boards section of the library to "2" from "1" but now I get the following error:

E (1814) vfs_fat_sdmmc: mount_to_vfs failed (0xffffffff).
E (2878) vfs_fat_sdmmc: mount_to_vfs failed (0xffffffff).
E (3943) vfs_fat_sdmmc: mount_to_vfs failed (0xffffffff).
Firmware started successfully
�[?25l�[0;0HCard Mount Failed

I am relatively new to the esp32 and would love to get your lovely code working. Any help would be greatly appreciated. Thanks!

Hey,

looks like you run out of memory. You could try to make for example the delay effect shorter/smaller. It might be also possible that the micro dip switch is not setup correctly. Did you check the switches?

Best regards,

Thanks for the reply! I now have everything loading properly and have enabled the midi stream player as a test. The serial port output shows me that the midi stream does play but I am not getting any audio from the headphone port on the audio kit. Almost there! Any help would be great. Thanks.

It might be possible that the I2S setting is incorrect. I2C is just the communication with the audio codec / controlling and setup of the codec. I2S is only the data which cannot be checked by the firmware.
