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!
