I'm running a dual boot computer with Ubuntu 18.04 and Windows 10. The sound on my computer has been working normally up until yesterday. I closed the computer lid and left to do something else, when I came back and opened it the sound stopped working. I only get a dummy output label on the sound output device. If I log into Windows, it can't find any sound output there either. I tried connecting normal headphones to the computer, but still I get no sound. Bluetooth headphones do work. Since the problem seems to be on both operating systems, I think the problem is with the sound card.
I'm trying to find out if I need to install a new sound card, or if there is something I can do to fix this issue. I think that since the sound does not work on Windows either, it is the sound card that is the problem. But I want to ask someone that might have a better grasp of this than I do.
To begin with I have to be honest and say that I tried lots of stuff I found online before I started documenting it. I used to (only checked this after the problem started) get something of the order
cat /proc/asound/cards -- No sound card detected---
The file has since been deleted by something I've done.
I tried doing the
sudo apt-get remove --purge alsa-base pulseaudio sudo apt-get install alsa-base pulseaudio sudo alsa force-reload
routine that I see in some solutions. Doing this used to run fine, but did not fix my problem. Now I get
sudo apt-get remove --purge alsa-base pulseaudio E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
I think this issue started after removing some old linux kernel headers using
sudo apt autoremove. Running
dpkg --configure -a starts the uninstall and install but it never finishes.

The terminal then hangs on this last line and nothing happens. Even after an hour nothing happens. The process can't be stopped or paused using CTRl+C or Z. I'm thinking that maybe it is trying to do something with the sound card and it doesn't work so it fails. Any ideas here?
Has anyone experienced a similar problem? Or does anyone know how I can fix this?
Here are some outputs from my terminal:
