How to reload audio, was working (20.04.1 LTS) and has now stopped working

Asked by David Barragan on 2021-01-18

My audio was working fine ... on lastest startup it stopped working ... it seems I have no drivers?

dvb@dvb-server:~$ inxi -A
Audio:
  Device-1: Intel 5 Series/3400 Series High Definition Audio driver: N/A
  Device-2: NVIDIA GF104 High Definition Audio driver: N/A

I've tried all the alsa and pulse audio fixes, I've tried the in BIOS->disable audio, reboot, bios->enable audio reboot ... nothing seems to work.

I've run the alsa-info.sh command and the resulting upload is: http://alsa-project.org/db/?f=06b566900bd524c5221cd157644eedc53916e815

Would really love some help trying to get this working again ... thanks!

I agree with your assumption that the driver package is missing.

It is not clear to me what the reason was for upgrading from the 5.4.0-* to the 5.8.0-* version of the kernel.
For solving the problem I suggest installing the package linux-modules-extra-(version-number)-generic

Try
sudo apt install linux-image-generic-hwe-20.04

Thanks Manfred Hampl, that solved my question.

Paul Omernik (leviathor) said : #5

I can confirm that installation of linux-image-generic-hwe-20.04 solved my no-audio issue on Xubuntu 20.04.1.
