[SOLVED] Pi Zero, PWM (analogue) output

[Nachteule]

Hmmm, the Raspberry Pi Zero Audio Circuit howto you're using sounds quite simple

Why are you adding

Code:

dtoverlay=audremap

dtoverlay=audioinjector-wm8731-audio

to your config.txt? IMO audioinjector-wm8731-audio overlay is needed for different audio sound card, so you should not add it.

I think adding

Code:

dtoverlay=pwm-2chan,pin=18,func=2,pin2=13,func2=4

is quite enough for audio part (and oc dtparam=audio=on, but this is enabled per default)
