Public bug reported:
I am using Ubuntu Focal in HP Pavilion g4, the internal speaker not
working, no sound at all. However it works if I run alsamixer and unmute
the headphone. It's strange that the internal speaker is assumed as
headphone.
For your information, it happens after upgrading to Focal, it was good
in the previous LTS version. For additional information, I upgraded to
Focal while using external monitor that has speaker by using HDMI cable.
The HDMI was connected before and after upgrade process. I don't know if
this is related.
