No Audio card detected (ACL892)

Hi,
I have a host with a Gigabyte MB B360 HD3P with Realtek ALC892 audio.
After install Proxmox 5.4.11 the system does not detect any Audio device or card.

APLAY -L OUTPUT
aplay: device_list:270: no soundcards found...

Any idea on how to enable it to detect the audio card/device?
We need it to enable audio on Windows VM.

Thanks
