  • Environment: Fresh installation of Ubuntu 20.04 on Dell Inspiron 5567 laptop.
  • Related softwares installed: VLC and FFmpeg installed (haven't had any problems with these)
  • Problem: Sound doesn't come out of the earphones.
  • Recent changes to the system: Installed ubuntu-restricted-extras.
  • Further details: Sound works on in-built speakers. On earphones, when sound supposed to come there's a one-time faint pop sound comes. And that's it. It detects as headphone and shows it emits sound on settings and it shows sounds are working on the scale. [image attached]
  • Special note: Everything works normally and sounds working on same earphones, same laptop on Ubuntu 20.04 live session.
  • Tried solutions: Removing ubuntu-restricted-extras didn't fix the problem. Tried to fix it on alsamixer no luck. pulseaudio shows the same results as the sound settings shows.

PS: Reinstalling the OS isn't an option right now.

Attached: Screenshot of the sound settings

    have you tried running alsactl restore afterplugging in headphones – ptetteh227 Jun 05 '20 at 15:48
  • @ptetteh227 thank you very much, it worked. – Nipuna Jun 05 '20 at 19:26
  • @ptetteh227 is there a way I can make this permanent? Because every time I start over after sleep or shutdown, it needs to restore again to make it work. – Nipuna Jun 06 '20 at 04:35
  • Please try this solution https://askubuntu.com/questions/50067/howto-save-alsamixer-settings and this http://manpages.ubuntu.com/manpages/trusty/man1/alsactl.1.html or even this https://ubuntu-mate.community/t/storing-alsamixer-settings/16953 – ptetteh227 Jun 06 '20 at 06:47
  • Thanks a lot again. sudo alsactl store worked. – Nipuna Jun 07 '20 at 08:19

for a temporary fix Run

to make it persistent so it survives a reboot run 

sudo alsactl store

Install "pulseaudio volume control"
sudo apt install pavucontrol
Launch it from menu or using "pavucontrol" command.

  • In "pulseaudio volume control" configuration tab, check "profile" is analog.
    In output device tab, test changing port to "headphone" or "speaker". Click the green button near "internal audio" .
    2 commands to reset pulseaudio config:
    mv .config/pulse .config/pulsebak
    killall pulseaudio
  • In alsamixer, check that "headphone" and "speaker" faders are muted and unmuted when connecting/disconnecting jack.
  • Another post indicates this fix : disable audio in bios, then enable again
  • if dualboot, disable fastboot in windows.

I updated to ubuntu focal fossa 20.04 from 18.04 and suddenly the sound and the mic stopped working.

As I am a beginner , I wasn't able to make correct changes in the alsa mixer . The other solutions in this post didn't work for me.

So, I use the following command to add the GUI version of the alsa tools. This can be done by the following commands:

sudo apt install alsa-tools-gui

hdajackretask

after this use the override option corresponding to the headphone and check the override option and apply changes.

If it works now, again reboot and check. In case , it doesn't work after reboot, you can use the Install boot override.
