Too bad :-(
Some questions:
1) Which Linux distro and which SDL version are you using?
2) Do you have multiple microphone inputs on your computer? E.g. a
direct mic on the Laptop and one in the dock? If so, could it be that
SDL uses a different default mic than PortAudio?

I tried to find these programs on the internet, but so far I failed ...
are these freely available somewhere?
I only tested the mic input with WHIP! and it was working fine for me
there.
> With the SDL2 version, the sound is garbage, it loops forever, ...
Is there anything recognizable at all in the "garbage"? Or is it just
random?
Something to try: I changed FRAMES_PER_BUFFER from 64 to 512 since 64
seemed to be a very small value for SDL ... does it work different for
you if you change it back to 64?
Could you maybe add a fprintf to the beginning of the
Microphone_Callback statement to see whether nLen contains sane values?
