Hello, I’m having the same problem where my built-in microphone doesn’t work anymore
I’ve try reinstall the sound driver from the manufacturer website. still no luck.
I’m using a laptop Acer VN7-591G.
I’ve tried to use the instructions above, but I was stuck at step 7 “Let me pick from a list of the device driver on my computer”. I cannot find ‘High Definition Audio Device” nor Realtec Driver as it’s default
