There is a common problem with Realtek ALC3306 on Linux (Kernel Bug 213159). This affects many Lenovo laptop models. For example, my fairly old Legion S7 15IMH5 laptop also does not work.
I'm not willing to pay $1000 for a fix (it's easier for me to buy a new laptop that will work with Linux), but $100 is probably okay. :)
$100 gets you a usb sound card and $90 for something else. It's not a good solution, but it's easy.
