Hi Guys,
I am trying to use my Rock Pi S as a Voice Assistant.
Audio out is working, but I cant get my Mic’s to work.
I have some simple electret Microphones here.
Tried to connect to Pin 23 and 24 at header 2, but no luck
Tried also several other combinations without luck.
(Pin1 to 23, etc.)
Do you have some hinds or ideas, what I am doing wrong?
Thanks in Advance
Kuumaur
