Dummy Output error for Ubuntu 19.10. Any idea how to fix it? The sound was lost at the last update. I use Acer Swift 3. Thanks

    Does this answer your question? Ubuntu 19.10 no sound – Pilot6 Mar 24 '20 at 18:48

  • This doesn't matter. I don't recommend using sudo gedit. At least sudo -H gedit, but it doesn't matter how you edit the file. – Pilot6 Mar 24 '20 at 19:03
  • I tried the commands recommended there but I keep on getting "command not found". I am not an IT person, so I have no idea what to do to fix it. Could you give me the right syntax? I am using Acer Swift 3 – MCI Mar 24 '20 at 19:17
  • Which command not found? – Pilot6 Mar 24 '20 at 19:21
  • sudo -H gedit /etc/modprobe.d/alsa-base.conf; I found sometning with "inexi" (I thing, but after reboot, I couldn't remember on which page I found that. – MCI Mar 24 '20 at 19:22
  • You probably are not running Ubuntu. Instead of gedit you can use e.g. nano. It will open a text-based editor. Ctrl+O to save, Ctrl+X to exit. – Pilot6 Mar 24 '20 at 19:24
  • I am running Ubuntu 19.10; GNOME 3.34.2 – MCI Mar 24 '20 at 19:25
  • You probably didn't understand. You run a command, an editor will open, then you edit the file. – Pilot6 Mar 24 '20 at 19:25
  • Clearly, I am not for this :(. Thank you for taking the time to answer me. Any idea if this kind of issue is going to be solved with the next update? – MCI Mar 24 '20 at 19:29
  • You can boot with a previous kernel using grub menu. I think this will be fixed soon. – Pilot6 Mar 24 '20 at 19:29
  • But the first time gedit started OK :-) see your first comment. – Pilot6 Mar 24 '20 at 19:30

    I have sound!!!It worked with: sudo gedit /etc/modprobe.d/alsa-base.conf; Add the following line to the end of this file: options snd-hda-intel dmic_detect=0 https://itsfoss.com/fix-sound-ubuntu-1304-quick-tip/ – MCI Mar 24 '20 at 19:55

You commented

I have sound!!! It worked with:

sudo gedit /etc/modprobe.d/alsa-base.conf

Add the following line to the end of this file:

options snd-hda-intel dmic_detect=0

[as suggested at] https://itsfoss.com/fix-sound-ubuntu-1304-quick-tip/

(In systems earlier than 19.10, you should use sudo -H gedit rather than sudo gedit)

This worked for me:

sudo apt-get remove timidity
sudo reboot
