I recently installed Ubuntu 19.10, wiping Windows 10, and my internal microphone isn't working. I tried installing Pulse Audio, alsamixer and there there is no internal mic being detected.
However, when I connect a headphone with a mic, it works fine. I also tried to add few combinations under /etc/modprobe.d/alsa-base.conf file, following a few blogs, unsuccessfully.
alias snd-card-0 snd-hda-intel
options snd-hda-intel model=auto
I tried things from the below link as well but unfortunately didn't work
Under alsamixer the card is HDA Intel PCH and Chip is Realtek ALC3204
Note: My Laptop config is like this
Any and all kind of help is appreciated.
PS: I am a newbie, who has just started to learn and my first step was to install the OS.
Edit – I have updated to the stable version of 19.10, updated all the possible updates and tried the above-mentioned steps. Unfortunately, my internal mic is still not being detected and as a result unable to use.

I have a Vostro 5490 from dell that has the acl 3204 chipset, the only way I managed to solve the microphone problem was to install the kernel
linux-image-5.0.0-1060-oem-osp1
