Comment 28 for bug 1840725

Same issue on Dell G3-3590 i7 gtx1660, worked for 2 months and now simply stopped, started without audio that i solved with this:

" I used to change /etc/default/grub to have this line

GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet splash acpi_backlight=vendor acpi_osi='!Windows 2013' acpi_osi='!Windows 2012' snd_hda_intel.dmic_detect=0"
Then run in terminal

grub-mkconfig -o /boot/grub/grub.cfg "

I get this solution from here:

Now audio works fine, with and without headphone. But the problem now is that the internal microphone is not detected. And when the headphone (with dont have microphone) is connected he is detected in input devices list as if it was a microphone.

and when I added this: options snd-hda-intel index=0 model=laptop-dmic
on: /etc/modprobe.d/alsa-base.conf

a internal mic appears in the input device list but still not detecting audio, and the headphone is not detected in the input list anymore, but audio still working...
