Bug Description
After Upgrading to Ubuntu 20.10 (From 20.04) I noticed, that my Audio Output didn't work anymore.
Switching between different Kernel Versions (Mainline 5.8.16 and Ubuntu Stock 5.8.0-25, 5.4.0-52) doesn't change that. Even on a fresh 20.10 Livesystem i get the exact same problem (On 20.04 Livesystem it works)
An Output of "$ lspci -nnk | grep -A2 Audio" shows that the Output device uses the wrong Kernel Module (Audio Input is working since it uses the correct kernel module and driver)

I have the same model and same problem. Nothing to add apart from a workaround which might be useful to address the problem, I hope.
1) I manually remove the module snd_rn_pci_acp3x.
Microphone stops working.
2) I restart pulseaudio with pulseaudio -k
Sound output starts working.
3) I manually reload snd_rn_pci_acp3x
Microphone detected and working again, without affecting the 'sink' (output).
On a side note, but somehow related, the led light of the mic button (F4) is always on, whether the mic is muted or not.
