-The audio controller seems to appear in "Other devices->Multimedia Audio Controller" with the small sign on it telling me there is a problem (driver) with it. I checked other device to see if there is something odd but all other stuff seems legit in Device Manager...

-Downloaded the driver from Lenovo website and double check it is the good one (there is so much similar name in Lenovo website...). 13S Gen2 ITL
