B450M PRO4 audio Realtek

The B450M PRO4 motherboard is sold with Realtek ALC892 codec audio as specified into manual and web site.
But I can't find it in Ubuntu 20.04 and Windows 10.
Into terminal with ~$ lspci the output is:
06:00.6 Audio device: Advanced Micro Devices, Inc. [AMD] Family 17h (Models 10h-1fh) HD Audio Controller

How I can enable the codec?
Thanks

I've seen various individuals getting some information about Realtek sound drivers recently, so you're not alone. I as of late experienced difficulty discovering them also, however, this driver page is by all accounts up and accessible at this point. Still bad that so many are experiencing issues. Considering the introduced base, I'm certain a genuinely critical number of individuals are unintentionally downloading malware from obscure "driver destinations".

Talking about introducing base and loathsome expectations, the assault surface by means of Realtek Audio drivers should be totally enormous. They're on what, likely 95% of all motherboards£ Since the drivers haven't been refreshed in more than 2 years and the conveyance strategy is aimlessly kept up, I question security is even on the radar. Notable individuals ought to likely be worried about that.
