I need some tips on how to set up guitar recording and playback with headphones together.

 

Simply: What is it that happens to receive audio on my guitar, using the Audio Port Input setting?

 

Follows is how I set up this rig.

I'm just trying to perfect it


Set up #1. I just plug in my acoustic electric guitar to my MBP directly with an 3.5 mm 4-Pin aux cord (with an 3.5 mm Mini to 6.3 mm 1/4 inch headphone adaptor in the guitar jack). Then I switch the Sound setting to use Audio port for Input. This form of set up feeds power to my guitar (I think) so the guitar mic works, allowing me to record on Garageband.


This setup would be adequate, but my acoustic is louder than my MBP speakers, thus any of the sweet pedals can't be adjusted properly. What I need is my headphones and guitar to use the same jack. So I got a splitter.


Set up #2.  I use a 3.5 mm 4-Pin to 2x 3-Pin 3.5 mm Headset Splitter Adaptor - M/F. The splitter is plugged into the audio port.

The guitar connection is sort of the same as #1, but the aux cord is plugged into the microphone side of the splitter and my headphones are plugged into the headphone jack of the splitter. This fully functions in recording and headphones when I turn on my built-in guitar tuner, but then it automatically shuts off for the battery.


Unlike #1, #2 set up doesn't automatically work to power my guitar, but like I said, it only works as long as my tuner stays on. There must be a way (a setting, or something) to make this set up work.


I know this is complicated, but it's been fun figuring out how all these things function. I'm almost there, but I could use some fresh ideas on how to combine the functionality of #2 with the power of #1.
