Just upgraded from Kubuntu 20.04 to 20.10 to find no audio device detected. lsmod shows module loaded, but alsa/pulse/etc is not picking up the audio device. If I boot using the old kernel that was left behind, it works (5.4.0-52 from 20.04). It does not work with shipped kernel (5.8.0-52) & does not work with kernel 5.9.1-050901 (the current unsigned kernel from mainline). lspci shows the device regardless of what I boot. lsmod also shows the driver loading, but I don't see the codec portion of the driver loading on the current and testing kernels.
