Headset microphone and laptop inbuilt microphone input is not recognized and wierd noise with video recording in native camera app

1 am using Acer Swift 3 – SF314-55G. It has
Intel i5 8th Gen
2GB of NVIDIA Geforce MX250 dedicated graphics.
8 Gb RAM
512 GB SSD

These are the problems I am facing with the fresh installation.

1. Headset microphone and laptop inbuilt microphone input is not recognized.
2. After Installation and update following drivers installation is suggested in the app center. Do I need to install them?
   

Update #2

These are the results
