So I have ASUS ROG G752VL laptop with Realtek ALC668 audio chip and OS Windows 10 pro x64 .
On internal and external (jack plug) microphone, when voice volume reaches approx. 70% microphone sound is normal, when bellow that, it lowers to fixed volume maybe 5% untill it is loud enough. I think it was Windows 10 version 1903 and earlier, when I installed ASUS audio drivers, worked normally, on official Realtek drivers voice was cutting out. When I went to version 1909, both drivers was the same. On linux microphone works normally. I tried from enabling and disabling effects, what ever I could in mic settings of Windows, tried troubleshooting, 30db boost works a little bit but still cutting out. Tried some stuff from the forums, nothing helped. I am using MIC on my headphones over USB, but I would like to be able to use external mic over the jack plug.
If anyone wants, I can make an recording, so you can hear it.
Please help.
