Question How to combine multiple inputs into one mic "input"

[UnsaidSleet4223]

I have an aux mixer and a mic that i want to use through the same input so i can blast music into calls while still being able to hear it, and i have things that work but they mess with other things. Any ideas

You may want to clarify what this mixer and mic you are using, and what are "things that work"? Calls as in through video calls on the computer?
