The soundcard I want to use is detected and works (it only recently switched to dummy output and didn't allow me to go back).
HDMI is no longer listed under Audio and Video – KDE Control Module; everything under audio module is set to dummy output and its the only 'soundcard' on the list now. I can view my previous sound cards in alsamixer, but changing the settings from there does nothing.
How can I get my real soundcards to work again?
I have already tried the following answers without success:

Could this image possibly help?:
There is another soundcard but I'm unsure of what its for because it never outputs sound, but it does have a lot of settings: that sound card is labelled as "HD-Audio Generic".
So I went into Software & Updates under the Additional drivers tab and I see this:
It was on Do not use the device so I changed it and applied the settings but unfortunately the soundcard isn't back even after reboot.

I don't know what's the problem or why it happens, but that worked for me.
