:thinking: hmmm ... this could be a tricky one. It seems that several problem reports are basicially complaining about similar "pops and clicks". My guess is that the problem needs...

@ChrisVeigl the NS4168 is an "external DAC" with built-in amplifier, correct? So the parts of your patch related to INTERNAL_DAC are not relevant for that configuration?

Hi, not sure if i2s_zero_dma_buffer() can be made into filling the buffers with anything different than 0 - it's part of the ESP-IDF, so we can't change it. . About...

Maybe no memory leak, however I see the problem that the class destructor may miss to uninstall the i2s driver, in case that `out->stop()` is used before `delete.` Nice catch...
