Problem with SD Card #575

Hey there,

I'm trying to build an MP3 Player with an ESP32-A1s and ESP32-audioI2S.
The Problem is the SD Card. I managed to start the Test Programm for the AudioKit and get an Output by Webstreams and audio.connecttospeach, but the reading of the MP3 or WAV from the SD Card is Failing every time:

09:30:05.801 -> .............Connected
09:30:07.150 -> RSSI: -69 IP: 192.xxx.xxx.xx
09:30:07.150 -> Connect to DAC codec... OK
09:30:07.150 -> info PSRAM not found, inputBufferSize: 14399 bytes
09:30:07.150 -> info buffers freed, free Heap: 123104 bytes
09:30:07.150 -> info Reading file: "/1.mp3"
09:30:08.046 -> info Failed to open file for reading

The SD Card is FAT32, 32GB and I can read and write the directories with the SD test Code.

Here's the code, can anybody help, to figure out my problem? Is there a Problem with the Files or the SD Card or anything else?

Thank you

But if I implement the WiFi in your Sketch again it gots the same problem...weird, I don't get it, but, I'll try to find a workaround.
