Hi schreibfaul1,

The latest ESP32-audioI2S v3.0.13d crashes on arduino-esp32 v3.0.7. Same code works OK on arduino-esp32 v3.0.5. I'm not an expert, but I think the problem is related to the latest changes in arduino PSRAM. The Exception Decoder points to Audio::setDefaults().

The hardware I use:
ESP32-S3 R8N2 at 240Mhz with 8MB flash at 80MHz (QIO) & 2MB PSRAM (QSPI).
