Which version of esp-idf are you using?

I'm using the version that installs with the ADF API.

I've given up trying to build this lot in windows it just doesn't work. Must have spent 3 very frustrating days on it. In Eclipse out of eclipse reinstalls etc etc. always some bug and msys32 takes minutes to compile even blink.

Fired up a linux vm under virtualbox and almost straight away i compiled a couple of the samples.

And now I have another problem.

the VAD example loads but apparently sees no MIC input.
