  • Please specify what version of Ubuntu you are on. 18.04 for example. Install pulseaudio volume control and see if you have any input devices capturing sound and any output devices. Play a video or audio and watch and see if anything is sending sound. – walttheboss Jul 07 '20 at 21:54
  • There is no sound at all –  Jul 07 '20 at 22:04
  • Have you install PaVuControl? And it does not see anything coming or going. – walttheboss Jul 07 '20 at 22:06
  • Have you seen the solution at https://askubuntu.com/a/1231693/612 ? – popey Jul 14 '20 at 22:22
  • @popey I tried that but it doesn't work –  Jul 14 '20 at 22:23
  • Try to re install base apps with these command. apt install --reinstall alsa-base alsa-firmware-loaders alsa-oss alsa-source alsa-tools alsa-tools-gui alsa-utils alsamixergui – Ahmet Özer Jul 24 '20 at 00:35
  • I wrote a tutorial to get everything, including sound, working smoothly on the Omen 15. It's for Manjaro KDE, but you might find it useful for your sound issues on Ubuntu too. https://medium.com/@claudio.cambra/troubleshooting-manjaro-linux-on-your-2019-hp-omen-15-gaming-laptop-august-2020-c570ced15ca8 – claucambra Aug 08 '20 at 16:46
