Internal speaker (Audio) is not working in Ubuntu 20.04 LTS after upgrading from Ubuntu 18.04 LTS

Question

I recently upgraded to Ubuntu 20.04 lts from 18.04 lts. After reboot audio is not working. I tried to reinstall pulseaudio and alsa but still not working. sudo apt-get install --reinstall alsa-base pulseaudio sudo alsa force-reload still not working.

Hi there i think we have the same problem...see https://askubuntu.com/questions/1230383/soundcard-not-detected-by-pulseaudio-but-by-alsa — user634093, Apr 24 '20 at 16:35

@InjamulMohammadMollah Doesn't work for me (Ubuntu Focal Fossa) — framontb, Jul 26 '20 at 19:19
This is silly but After days of searching, upgrading from 18.04 to 20.04 then installing fresh 20.04 i was not able to solve the problem, which finally got solved by just going into BIOS -> disable Internal Speakers -> apply changes -> Enable again -> Apply changes -> Exit.

Your speakers may be detected as unplugged which causes them to be ignored.

Temporary fix:

sudo apt install pavucontrol
Run pavucontrol
Configuration tab > Profile > Analogue Stereo Output (unplugged) (unavailable)

Speakers should work but it will reset when headphones are unplugged or system rebooted.

Permanent fix:

sudo apt install alsa-tools-gui
Run hdajackretask
Parser hints > jack_detect = no
Apply now
Install boot override

The second one worked for me, even if there were error messages when I applied it. – billy May 14 '20 at 11:22

Tried everything for asus zenbook pro ux434f but didnt work. Finally permanent fix worked for me after a restart (didn't installed boot override though).
I will read the documentation and would then install boot override.

Just in case somebody reached this question looking for a solution. The only native solution (no need to do something external) is provided by @Nate on this link https://askubuntu.com/a/37609/9598 which I reproduce partially here to give you a clue on how to fix this problem.

I [...] noticed that the ACLs weren't set in /dev/snd

sudo setfacl -m u:$USER:rw /dev/snd/*

and then do a reboot of your computer.

Running this command in a terminal will fix the issue.

Thank you very much Michael Butler

it worked to me, after a reboot. – luca76 Sep 15 '20 at 05:27
This worked for me too – ubuntuUssser Aug 01 '21 at 08:56
How to make it permanent? When I reboot this fix is gone. – ubuntuUssser Aug 01 '21 at 09:19
I don't know under which circumstances it is removed on reboot, but you can add this command to your crontab using sudo crontab -e then add @reboot setfacl -m u:$USER:rw /dev/snd/*. Maybe you are using a removable sound card? If so, just make sure your sound device is ready on start. Otherwise you may need to wait for a while sleep 60 (for 60 seconds delay), before the command runs. – Geppettvs D'Constanzo Aug 04 '21 at 18:33

I think i have a workaround for your problem: Try

sudo alsa force-reload

This brought my soundcard back to life. But it doesn't survive a reboot, so I am working on making the change persistent... See:

I already tried this.. see at question – Injamul Mohammad Mollah Apr 24 '20 at 19:34
this works for me on Dell XPS L502X, and keeps working after sleep. – geoffrey Apr 29 '20 at 18:20
@geoffrey, why shouldn't it be working after sleep? – Alexey May 04 '20 at 08:37
Well because it's said that it doesn't persist after reboot. I don't know the internal working. I just wanted to add the info, maybe it could help someone diagnosing the problem better. – geoffrey May 05 '20 at 09:08
@geoffrey, reboot has nothing to do with sleep. Sleep changes nothing, your comment almost certainly will not help. – Alexey May 16 '20 at 13:26

What fixed it for me after an upgrade to 20.04 was:

sudo apt purge timidity-daemon

Then reboot.
Quick and easy so worth trying!

That helped. Dell XPS here. Can you explain why? – Ville Laitila Sep 02 '20 at 20:36
Wow !!! Thanks for the trick !!! – Cedric Nov 07 '20 at 16:59
Ha, this was exactly my case. I installed timidity yesterday, and today sound disappeared (failed to switch back). Removing timidity fixed it... – Ilia Andrienko Nov 27 '20 at 09:03
Kernel:5.4.0-90-generic. After that I added options snd-hda-intel model=generic and reboot, nothing. After that I changed in options snd-hda-intel model=auto and added options snd-hda-intel dmic_detect=0 (in /etc/modprobe.d/alsa-base.conf), and blacklisted blacklist snd_soc_skl in /etc/modprobe.d/blacklist.conf and a reboot... nothing again. Then after sudo apt purge timidity-daemon and sudo alsa force-reload did it without rebooting again. – Hastur Nov 27 '21 at 19:54
I made apt purge pipewire. inxi -SMA then reports PulseAudio server instead of PipeWire and the sound works in my case. – mirek Mar 22 '23 at 13:47

Mine is a Dell Inspiron 1525. I tried all the solutions listed here on askubuntu.com and all over the web but of no use and finally to find that it is a bug in Ubuntu 20.04 LTS/kernel-5.4 (Focal kernel) where the internal sound card is not detected. The driver soc-skl is disabled by default from kernel-5.4. Kernels 5.5, 5.6 all disabled this driver. Read the bug reports here and here.

It affects many users. There is nothing much we can do until the kernels are fixed.

For me, the headphones and mic are working. For the time being, connecting the headphone jacks to external speakers solves the problem.

@Greg gave me The patch which is working for me

sudo add-apt-repository ppa:kaihengfeng/fix-lp1869819 sudo apt-get upgrade

Now Sound is working fine.

I had this problem and tried everything else. For me the problem was built-in front audio in a desktop: it stopped working after a reboot. Running aplay -l said it saw no cards, but lspci -v reported an Intel Corporation C610/X99 series chipset HD Audio Controller. Its output didn't include any lines for Kernel modules. Googling told me that other people were using snd_hda_intel as the driver, but lsmod | grep snd gave no results. I didn't even have a /proc/asound directory; it was just missing.

It turns out I needed to run this to install the missing driver:

sudo apt-get install linux-modules-extra-`uname -r`

I actually did have the drivers installed for a previous kernel (visible if I said find /lib/modules -name 'snd-hda*'), but for some reason I didn't have the -extra package installed for my current kernel.

Hopefully this helps someone!

This fixed on my dell laptop the problem with sound, wifi network and hdmi output not working problem after upgrading from ubuntu 18.04 to 20.04.3. For some reason, during upgrade, the -extra package didn't got installed — Claudiu, Sep 12 '21 at 14:24
