18.04 audio (Realtek ALC3254) fails on new Dell G3 15 3590

Solution 1:

Im using Ubuntu 18.04 Dell G3 3590 i7 series

I just follow the instruction here and fixes my problem

Edit /etc/default/grub

sudo vi /etc/default/grub

Find the line starting with GRUB_CMDLINE_LINUX_DEFAULT and append snd_hda_intel.dmic_detect=0 to its end. For example:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_hda_intel.dmic_detect=0"

Update grub configuration

sudo update-grub

Reboot

Solution 2:

--- UPDATED VERSION ---

As of Nov. 29 of 2020, update on Ubuntu 20.04 with latest kernel of 5.8.0-25-generic is working as expected with all internal sound working. Basically if you modified your grub with snd_hda_intel.dmic_detect=0, erase that or other modifications you made and keep the system fresh.

Update and upgrade with apt and now it is working with the internal mics and speakers.

So basically, update your vanilla 20.04 with latest kernel and updates and should work.

--- OLD REVISION ---

THIS IS WHAT WORKED FOR ME,

DELL G3 3590 is certified in Ubuntu 18.04 ONLY. It's very weird that later versions break functionality in this laptop.

The Dell G3 3590 version I have is the revised one (2019 version) but I guess the older 3590 version should work as well.

Do not install Ubuntu 20.04 or other version except 18.04 on this notebook.

I just did a Fresh install and at first sound wasn't working, then a Automatic Update at first boot (it's common when fresh install to get an update) added the sound and microphone working. If not, just apt-get update && apt-get upgrade

Then I added additional drivers for Nvidia and is working nice.

UPDATE On February aprox. a new version of ubuntu was released (18.04.4) and it has an optional upgrade called HWE that contains newer kernel and stuff. My solution worked but in some point, audio from the headphone jack was missing.

running sudo apt-get install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04 solved this issue. So I have fresh install ubuntu 18.04.4, updated it and finally updated to HWE and have all sound working! internal and external as well.

WHAT A RIDE!!!
