That doesn't seem quite right, are you sure you set your strip mode correctly (GRB vs RGB, etc...)?

It should take the default recording device, I’ve used it fine with line in though I may have had to set line in to be viewed as a microphone device...

Oh hmm, I haven’t tried that setup on RPI before only on windows so I’ll have to default to someone more knowledgeable on this one, unfortunately.

Do you have the python part?

Do you have the rest of this? I would love to try implementing this a little better.

The visualization tries to add a sort of gain to the audio when it's quiet to deal with microphones that don't pick up audio well, and in doing so it...

As far as your other questions, I do not own a rpi so I can't assist but its possible someone may have figured that out in another issue?

Did you install the dependencies as shown in the instructions?

Yes, please follow the instructions and install all the dependencies before trying to run it.

Sounds like PyAudio didn't install correctly then.
