I fix it on ubuntu 19.10, maybe work on ubuntu 20.04

FIRST: do

arecord -l
maybe gives:

**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC3254 Analog [ALC3254 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

NOTE: Subdevices: 1/1, remember it!

SECOND:
add
    options snd-hda-intel index=X model=laptop-dmic
to /etc/modprobe.d/alsa-base.conf

NOTE:
if Subdevices: 1/1, index=1
if Subdevices: 0/1, index=0

after update alsa-base.conf, reboot!

try it!
