Windows 10: Why is my Line in not showing up

I use an auxillery cord to connect my main display to my pc so that I can listen to xbox sounds through my pc headset while talking in discord or doing anything else on my pc. I recently rearranged my desk so I unplugged everything, and when I plugged everything back in my line in input in my sound mixer did not show up. The cord was working fine a couple days ago, and I cant get the device to show up in my settings. I have looked on here and many fixes have mentioned updating audio drivers, I do not see this in the command center. not sure what to do now.

:)

 

GPU-Z what command line parameter ?

Suggestion: /? (-?) and /help (-help) command-line arguments to show a list of all possible arguments in a small window. *Smile

 

GPU-Z what command line parameter ?

Current /? (-?) or / help (-help) parameter is invalid

Step 1: I suggest you to run SFC scan,
System File Checkeris a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files.

Follow the below steps:

• Right click on the Start button, click on
  Command Prompt (Admin).
• Type “sfc /scannow” without the quotes and hit
  Enter.
• After the scan, restart the computer and check for the issue.

Step 2: Also, I suggest you to update the display drivers and check.

Steps to Update the Display Adapter driver.

• Press Windows key + Xkey when you are at desktop.
• Select Device Manager.
• Expand Display Adapter.
• Right on the Display Adapter and click on
  Update driver software

BUT i still have the line on screen.
