Troubles with getting aux in about arduino-audiokit HOT 2 CLOSED

I suggest you have a look at the examples which read audio (e.g. this).
There you see how to specify the input device with AUDIO_HAL_ADC_INPUT_LINE2 or AUDIO_HAL_ADC_INPUT_LINE1

from arduino-audiokit.

Thanks a lot, you savaed me a lot of time trying useless tings, it was a lot easy then assumed.
It seems like LINE_1 are the microphones and LINE_2 is the aux in. (LINE_IN mode is probably internally sending the line_in directly to the outputs without sending them to the esp)
Maybe it would reduce confusion to clearly mark this in code, I found the description mic input to adc channel 2 and the name AUDIO_HAL_CODEC_MODE_LINE_IN at audio_hal.h (line 66, 73, 74) especially confusing. (Shall I do a pull request for that)

A few more little things:

1. Do you know why after uploading to the board, it first continues executing the old code, untill I press RST?
2. Is it possible to reduce the background noise? (When I stop my audio source I hear some)
3. When uploading it allways doing the old Connecting......_____......_____....... stuff, and only stops after pressing BOOT + RST, is there a way to prevent this?
