It would make both of the speaker and headphone works. I assume if I can find the correct model. I tried model=auto and model=dual-codecs, but still no luck. However, my built-in speaker still didn't work. I was able to fix sound output on headphone by running the following command echo "options snd-hda-intel model=generic" | sudo tee -a /etc/modprobe.d/nf I installed Ubuntu 20.04 and 22.04 and both have no sound output on built-in speaker and headphone.
