I would also like to know this. I have a Lenovo Legion and the sound quality is dramatically worse on Linux vs Windows. A fix would be a godsend.

Windows drivers (Realtek?) likely load EQ coefficients into the codec, while the Linux one doesn't.

There are some tools and info here on how to get the coefficients you need (it's Hackintosh-oriented, but the basic principles apply):
