Aurora R15, listening to input from the Jack Mic on a headset

Hello,

I am trying to connect my TV to the PC so I can listen to the TV sound through the headphones connected to the PC.

I have the an output from the TV plugged into the 3.5 Jack Mic. However, there does not appear to be a way to get that input to play on the headphones. Am I missing something in Windows 11?

My goal is to have the headphones play both the computer sound and incoming sound from the Jack Mic.
