I ended up doing the work myself, however only AudioGeneratorWAV, AudioFileSourceSD, AudioOutputMixer, and AudioOutputI2S works. This issue will remain open unless it is not feasible to include C support.

Do you mean this file? https://github.com/micropython/micropython/blob/master/ports/esp32/modules/flashbdev.py I would not worry about keeping a reference to this file. That executes at boot to mount your flash VFS at root. However it's...

It looks like you're trying to wait for 86.4 billion microseconds. Is there a reason why you are using time.sleep_us instead of time.sleep(24*3600)?

Hello jamesquilty! It would be great if you could provide a decoded backtrace! I cannot help without one.

@jamesquilty Unfortunately, right now I do not have access to xtensa-esp32-elf-gdb. I have yet to install it on my windows system. I was using a RPi for a while to...

Based off of your register dump, I can identify a few things: Exception: LoadProhibited (we're trying to access an invalid memory range.) PC: 40116de: Valid IRAM/IROM address. A0 (I believe...

I found a little more information here at https://github.com/micropython/micropython/blob/master/ports/esp32/machine_sdcard.c The function sd_deinit appears to be the culprit. ``` STATIC mp_obj_t sd_deinit(mp_obj_t self_in) { sdcard_card_obj_t *self = self_in; DEBUG_printf("De-init host\n"); if...

Since I apparently disabled machine.SDCard support on my board when I compiled my code, I was unable to reproduce the crash. If it is possible to migrate your code base...

That is very helpful. So it does appear to be an issue in IDF. If it would be possible, could you paste only the backtrace in the decoder? This would...

If you omit the "Backtrace:" will it work?
