right, thanks I overlooked that I should actually use I2C!
I tried to run the code proposed here instead but also without any luck.

After the 3 time stepping into audio.loop() it fails with Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled.:

Is there anything I’m doing wrong? The issue seems to be too much data loaded into memory?
