UDA1334 i2s DAC with ESP32 - sketch too big

Code: [Select all] [Expand/Collapse]
  1. I am trying to implement a web radio streaming device with ESP32 (DEVKITV1 from Aliexpress) and UDA1334A DAC. The problem is that when compiling in the Arduino IDE (2.3.3 nightly) I get the "sketch too big" error:
  2.  
  3. [quote]Sketch uses 1356645 bytes (103%) of program storage space. Maximum is 1310720 bytes. [/quote]
  4.  
  5. The sketch from this source https://electropeak.com/learn/interfacing-uda1334a-i2s-stereo-decoder-module-with-esp32/ is actually garbage, does not even compile. I made it try to compile (with the too big error) by adding the missing "()" in every single function.
  6.  
  7. The sketch from this source https://how2electronics.com/simple-esp32-internet-web-radio-with-oled-display/ actually tries to compile (gets the too big error), I even stripped it from the display part to try and save space.
  8.  
  9. In the Arduino IDE I tried to select both "uPesy ESP32 Wroom DEVkit" and "DO IT ESP32 DEVkit V1" as boards, no difference (still get the "sketch too big" error).
  10.  
  11. Any ideas as to why a sketch supposedly working (from a tutorial) does not compile?
  12.  
  13. EDIT: This is the full code that tries to compile (but still is flagged as too big of a sketch):
