January 21, 2021, and the issue is still not resolved.
LG GRAM owner here.
I contacted LG and they don't provide any solution/updated driver either.
The support service response was to download a "REALTEK" audio driver for another laptop model. As if a Realtek driver had anything to do with Conexant.
Really pissed off, since the laptop is a 2019 model and not able to update Windows anymore.
I contacted live Microsoft support and a guy told me "Run the Windows updated manually using the media creation tool". It seems they don't even know their own advice of not doing that because the computer will crash...
