PCI/internal sound card not detected

[wasimakram]

Problem: My audio is not working. I'm getting that "Dummy Output" in the sound settings. I've been scouring the web, but nothing I try is working. I've tried

sudo alsa force-reload

sudo apt-get remove --purge alsa-utils

sudo apt-get install alsa-utils

I've tried about every single little thing, and it's driving me crazy.

(wasn't quite sure how much you guys needed)
For some reason, I don't have a .asoundrc file or /etc/asoundrc.conf file. I can't get into alsamixer either. I've uninstalled, reinstalled, uninstalled, and reinstalled alsa-base, alsa-utils, pulseaudio, and even Wine.
I don't know what else to do at this point. Can you guys help me?

EDIT: sudo alsa force-reload returns

 Unloading ALSA sound driver modules: (none loaded).
Loading ALSA sound driver modules: (none to reload).
Do I have to reinstall Ubuntu?
