Hi, Yes, I'm also trying to eliminate the popping sounds. Everything works for me, without any popping sounds! |

When I use the AudioOutputULP.h library, I get an error on Build/Compile:
undefined reference to `vtable for AudioOutputULP'
Full message:
It compiles fine using the AudioOutputI2S library (using internal DAC)
output = new AudioOutputI2S(0, 1);
, but since I'm using the internal DAC, I would like to free up my I2S and also attempt to prevent popping as noted here in issue #406 .I also tried using this branch without sucess:
