I have a Dell xps13 that previously had 14.04 and the sound worked fine. I recently installed 18.04 and now I have no sound through either my speakers or headphones. The sound settings look like this: enter image description here (Note that there is no 'Test Sound' button. )

[Edit] I've already tried many of the fixes I've found on AskUbuntu, including:

  • pulseaudio -k && sudo alsa force-reload (nothing changes)
  • I've tried reinstalling alsa and pulseaudio. [/Edit]

I'm now following the Ubuntu troubleshooting guide for sound.

At step 3, entering wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && ./alsa-info.sh yields the output: https://pastebin.com/raw/44UDnp63

Running the code in step 4 yields https://pastebin.com/raw/YinifjQC

I've checked with pavucontrol to make sure that nothing is muted. This is what the panel looks like:

(The lower bar indicates that sound is playing, but I don't hear anything out of the speakers/headphones.)

Please help!

Edit:

As per Muntaha's suggestion, I tried

mv ~/.config/pulse ~/.config/old_pulse

and restarted. Now I have only dummy output listed:

enter image description here

The standard answer online to fix the 'dummy output' problem is to run pulseaudio -k && sudo alsa force-reload but this does nothing. Trying to figure out what to do now...

Further edit:

As per the solution to this question "Dummy Output" No sound in Ubuntu 16.04:

In the end, I rebooted into the bios and disabled the built-in audio, applied those changes, rebooted to Ubuntu, then rebooted again into the bios to re-enable the audio. Once back into Ubuntu after that, everything seemed to work great!

This also worked for me!

  • You can try this command: pulseaudio -k && sudo alsa force-reload – WinEunuuchs2Unix Apr 10 '19 at 23:53
  • I've tried that already (see edits). Have any other ideas? – Mark Girard Apr 11 '19 at 12:51
  • why 18.04 specifically? like why not 19.04 (in exatly 7 days) or 18.10? let's try running you through some solutions for 18.04, if you're dead set on it : you could update the system if you haven't already with sudo apt full-upgrade -y you can also upgrade the kernel sudo add-apt-repository ppa:teejee2008/ppa -y && sudo apt-get update && sudo apt-get install ukuu -y && sudo ukuu. – tatsu Apr 11 '19 at 13:02
  • I'd like to know if the sound works via HDMI attached. If so, maybe there is one switch to activate/deactivate the internal speakers. Maybe alsamixer on the console/terminal could help to try the possible switches. – LupusE Apr 11 '19 at 13:09
  • same problem, https://askubuntu.com/questions/1134314/dummy-output-in-ubuntu-16-04-after-fresh-install – Maruf Apr 17 '19 at 09:11
  • @LupusE It still does not work through HDMI. – Mark Girard Apr 18 '19 at 18:14

Go to your home directory and then go to the hidden config directory. Rename the directory named pulse here:

mv ~/.config/pulse ~/.config/old_pulse

Now reboot your system. The pulse directory should be created afresh and you should have sound.

  • I did this, then all I saw was a dummy output. Then I used the solution in thie post https://askubuntu.com/questions/914463/dummy-output-no-sound-in-ubuntu-16-04. Namely, I rebooted into BIOS to disable all audio, then reboot and reenable all audio. Now I've got sound! – Mark Girard Apr 18 '19 at 18:46
  • well i'm glad to know it worked.. enjoy! – Muntaha Liaqat Apr 18 '19 at 21:26

Another Solution for you it the above one didn't work for you...

Open the terminal and edit speech-dispatcher file by using the following command:

sudo gedit /etc/default/speech-dispatcher

In here, change RUN=yes to RUN=no

Reboot and enjoy the sound

https://help.ubuntu.com/community/HdaIntelSoundHowto#Playing_with_probe_mask seems to work for me; I've added the following two lines to /etc/modprobe.d/alsa-base.conf:

options snd-hda-intel model=generic
options snd-hda-intel probe_mask=1

... and rebooted (after trying various other tips so YMMV).

What I found was to remove the timidity-deamon:

sudo apt purge timidity-daemon

Thanks to Aaro Alhainen for his post.

You can read about timidity-deamon.
