Re: Why does Audacity show me internal mics: "Internal Mic: 0" and"Internal Mic: 1"?
I want to know why I have got two internal mics? As far as I know, my laptop has got only one internal mic.
At the bottom of that page is a link to a datasheet where you can find a
diagram of the chip. It has indeed two channels for microphones.
What a laptop manufacturer does with those two inputs is an open question.
