#StackBounty: #sound #20.04 #pulseaudio #alsa #microphone No speakers, no microphone, but headphones @Dell Lattitude E6530 (20.04)

Bounty: 50

This used to work @18.04 LTS but stopped working at some point, so I decided to head for the newer 20.04 LTS, but the problem persists.

What I tried:

  1. reinstall alsa-base and pulseaudio https://superuser.com/questions/1451847/sound-stopped-working-ubuntu-18-04
  2. rename alsa-base config https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1770429
  3. remove pulse config No sound in Ubuntu 18.04 LTS after upgrade from 16.04 LTS

None of these solutions work.

Interestingly if I run pavucontrol, while yt is playing a video, I can see an amplitude, but I can’t hear a thing. If I connect headphones it works as expected.

#StackBounty: #grub2 #nvidia #20.04 #grub-efi #nvidia-geforce Cannot install Ubuntu 20 on laptop with windows 10 and NVIDIA Geforce RTX…

Bounty: 100

I have laptop with NVidia Geforce RTX 2080 and Windows 10 installed, and I would like to install second OS, latest Ubuntu 20, but I am not able.

Black Screen after launching Grub option "Ubuntu" or "Ubuntu (safe graphics)".

I have read a lot of articles and posts about problems with installing Ubuntu on laptops with NVidia card, all regarding Ubuntu versions up to 19, not the latest one (20). I know that I should turn off Fast Startup in Windows 10, to disable Fast Boot and Safe Boot on UEFI. I know that there are problems with Nvidia card’s Nouveau drivers and how to set "nomodeset" (nouveau.modeset=0). What is important, the latest Ubuntu version addresses this issue with new Grub option called "Ubuntu (safe graphics), where "nomodeset" is set by default.

But It does not help, Black Screen as usual, no any logs on screen.

Was anybody able to install latest Ubuntu 20 on laptop with NVIdia RTX card?

How to get logs from installation process to get known what is going wrong?

#StackBounty: #drivers #sound #kernel #20.04 #alsa Only "Dummy output" (sound) in Ubuntu 20.04 after reboot

Bounty: 100

I am using Ubuntu 20.04 for over a month now.
After a reboot, I have no more sound and WiFi. Note that this is different from many other posts, which seem to have had no sound at all, after an upgrade. In this case, sound stopped working only after a reboot.

As for the sound, I seem to not have the appropriate kernel modules for sound, so I guess the most likely solution would come from making the modules available (it seems I have two sound cards).
I will try to include as much info as possible related to the copious posts with similar problems.

This is what I see.
