Ubuntu 18.04 LTS dummy output

Question

So my device output was working fine until one day suddenly it just said dummy output. I then mistakenly upgraded Ubuntu as well. Until recently Bluetooth headphones were working but now even they have stopped working. Only wired headphones are working. I tried pulse audio purge remove, killall, start, remove ~/.config/pulse, alsa force-reload, and rebooting my device but none of the methods have fixed my dummy output problem.

lspci -nnk | grep -A2 Audio

gives no output

and no sound cards are detected

cat /proc/asound/cards

returns no sound cards

Apologize if questions is framed in wrong or incorrect way, it's my first time.

sudo reboot
