Low mic volume when using 3.5mm jack (RealTek). | "Result 1% of total volume" - FIXED

This was tested on an 11th Gen X1 Carbon with Realtek audio. Issue was seen on 3 brand new units. Disabling enhancements, increasing mic boost, updating drivers and doing everything in between did not help. The only solution was to change the driver for the Realtek audio device from a Realtek driver to Microsofts High Definition Audio Device driver which corrected this issue on all machines.

1. Open Device manager
2. Scroll down to Sound, Video and game controllers
3. Right click Realtek(R) Audio and select "Update Driver"
4. CLick Browse my computer for drivers
5. Click Let me pick from a list....
6. If Microsofts High Definition Audio Device is shown select it and click Next to finish installing. If its not there;
   a. Uncheck the box that says "Show compatible hardware"b. Look for Microsoft in the Manufacturer list thats shown and select it
   c. On the right hand side under the Model list, look for "High Definition Audio Device", select it and click Next.
   Note: It might say "version" at the end and may have multples. If there are multiples select the last one in the list as that should be the most recent driver.
7. After the new driver installs and you'll be asked if you want to restart, select Yes.

You should now hopefully get the expected volume levels from the Mic.

Thank you!!
Been wrecking my brain about this for weeks!
