Ubuntu 19.10 Dummy Output error

Question

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

Answer 1

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)

Answer 2

This worked for me:

sudo apt-get remove timidity
sudo reboot
