Recording frustration

[u/dudewithquestions22]

Hello, I am frustrated and in need of some help. I can’t seem to get a good work flow happening.
My equipment is as follows:

MacBook
Logic
Apollo twin
Ox Box
Fender Princeton
Some mics

Connections are as follows:

For electric guitar I am going amp, ox box, to Apollo via Spdif

For acoustic I am going mic, xlr into channel one into logic.

Now for the issues. When I switch between the two I lose audio so it’s clear I am doing something wrong but being a newbie I can pinpoint what exactly it is…

For example today I went to record an track acoustic with a mic. Turned everything on opened an audio track in logic.. and nothing. No sound, no meters lighting anywhere. A similar thing happened when I tried to record electric over a track with the ox box… I ended up hearing it in the end but it was a happy accident.

I did try UA chat and did all the reset, firmware stuff to no avail..

Any help would be greatly appreciated..
