esp32 wroom always read 0s from ICS-43434

Postby bwendin » Tue Jan 10, 2023 10:51 pm

I'm using ESP-WROOM with audio chip ICS-43434. Pins are attached: SCK to GPIO4, SD to GPIO36, WS to GPIO33. L/R is grounded. i2s_read() always returns 0s. I've tried many things, altering i2s_config but cannot get non-0. Am I dong something wrong? Maybe I can't use GPIO36? I'm using esp-idf v4.4.1.

I've attached sdkconfig and main.c.
