The problem of speaker volume is  a known issue. And if the speaker 
could work, it means the the kernel + firmware works.  We also need to 
manually install/upgrade alsa-ucm-conf and the pulseauido-13.99, then 
the mic will work. There is already a public bug to track integrating 
the alsa-ucm-conf into the 20.04 image.
