Sorry, that suggestion was based on the package not being in Ubuntu 18.10. I did not realize it is a required package in 18.04.
To fix what was removed by the previous command you can reinstall the missing packages by running: sudo apt install cheese gnome-control-center gnome-initial-setup gnome- video-effects gstreamer1.0-plugins-good libasound2-plugins libcanberra- pulse libcheese-gtk25 libcheese8 libjack-jackd2-0 pulseaudio pulseaudio- module-bluetooth rhythmbox rhythmbox-plugin-alternative-toolbar rhythmbox-plugins totem totem-plugins ubuntu-desktop ** Changed in: pulseaudio (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1802402 Title: [UX430UNR, Realtek ALC294, Black Headphone Out, Left] No sound Status in pulseaudio package in Ubuntu: New Bug description: I expected speaker and headphones to work.
