Add a line in?

With the release of the schematics is there a possibility to add a line in for a microphone anywhere.

I’m comfortable modifying the hardware but I’m not confident enough to decide what/how to modify.
I’d have to check software wise how possible it would be to add it in.

Maybe just a direct pass through with a physical button if needed if setting it up as one of the streams wouldn’t work.

Any suggestions or ideas for this?

Hey, unfortunately, you cannot just add a line-in since you’d need an ADC for that.

The only way I see you could do it is by adding an i2c ADC chip and then modifying the code to read the analog signal using it
