Audio not working on Ubuntu 18.10
0
Audio has been working on my system (dual-booted windows and linux) for a while, but yesterday it just randomly started saying "No output or input devices found." I have tried suggestions everywhere on the web but nothing works. If I run lspci I get:

Please help me fix this. Thank you.
UPDATE: I found out using 'alsamixer' I can change volume and sond works but KDE Plasme doesn't do anything and doesn't recognize the sound card.
Thank you.

If you are seeing the hardware and alsa devices, and more importantly can hear sound when you play music files, I suspect there is something wrong with pulseaudio. Have you tried to reinstall it withsudo apt purge pulseaudio && rm -rf /etc/pulse && apt install pulseaudioand then reboot?
