options snd-hda-intel model=asus-zenbook,auto

If NVIDIA is card 0 and PCH / ALC294 is card 1:
options snd-hda-intel model=auto,asus-zenbookThat fixed the internal speakers for me on the ASUS ROG Strix G512LW with Realtek ALC294 and RTX 2070 Mobile / Max-Q.Hopefully this helps someone else with the same cursed little audio gremlin.
