Hello people

I actually have a problem to compile and program the sample code from XT_DAC_Audio on a ESP32
I use Arduino IDE 2.2.2
I have downloaded the archive : https://www.xtronical.com/wp-content/up ... -4_2_1.zip
I have downloaded the board ESP32 Dev Module

When I try to verify the sample code "PlayWav" from the archive, i get this error message :

collect2.exe: error: ld returned 1 exit status

exit status 1

Compilation error: exit status 1

It looks like something is not well referenced, but i don't why, because i took everything from the archive and added it to library
Can someone has a clue or an idea of what i can/should do to success

Thanks in advance

I installed with git from https://github.com/WeekendWarrior1/XTro ... dio_Mirror
Compiled without problems. Perhaps you did not put it in the correct location where it could find the functions. (<sketchbook>/libraries/XT_DAC_Audio - it is flat in there)
The include in that playwav.ino really should be #include <XT_DAC_Audio.h> to indicate it is a system provided header rather than local, but that should not cause an error.
