Ubuntu 20.04 No Sound

I’m running Ubuntu 20.04 LTS on a Dell G3 15 3590 and It’s mute. On pavucontrol all outputs shows (unplugged) (unavailable). I had already tried lots of solutions on web, but nothing works.

pacmd list-cards returns this
my pavucontrol looks this
alsamixer looks this

nvidia-smi returns

Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post. You will have to rename the file ending to something else since the forum software doesn’t accept .gz files (nifty!).

Please remove ‘nomodeset’ parameter. You’re running on FBDEV vga fallback driver, no outputs will work.

Without “nomodeset” my system doesn’t boot. It freezes on Dell loading screen.

Please follow this:

  • boot without nomodeset
  • after freeze, reboot, set nomodeset in grub to be able to boot
  • right after reboot, run sudo journalct -b-1 --no-pager >lastboot.log
  • attach the output file

Looks like the i915 driver is missing completely. Please run

sudo apt-get install linux-modules-extra-5.4.0-29-generic

and check if you can then boot without nomodeset.

It returned:

Odd. Should be installed, then.

and the last one didn’t returned anything.

Seems it’s installed and not blacklisted. Odd. Please try updating the initrd
sudo update-initramfs -u
and check if it then boots without nomodeset.

I didn’t understand the return

update-initramfs: Generating /boot/initrd.img-5.4.0-29-generic
I: The initramfs will attempt to resume from /dev/sda6
I: (UUID=155501fe-c6ac-477d-8ffe-546822b93f4e)
I: Set the RESUME variable to override this.

That’s just an informational message which partition will be used for suspend-to-disk.

Alright, gonna reboot now

So, in the first time I rebooted it passed through the Dell loading screen, but once I put my password, screen went dark. I rebooted once again and then it frozen on dell loading. Again I rebooted and put the nomodeset, and even then system is freezing. I’m texting from my phone now. Also got this messages in one of the tries.

once again received this, guess it’s why it freezes, nothing more happens after this

Something is very wrong with your intel gpu or the driver for it. To get back into your system, try adding

modprobe.blacklist=i915 nomodeset

to the kernel command line.

It didn’t work

Does safe mode from grub still work?
