Okay so I plugged in a headphone, and then the sound stopped working. I took the headphone out and the sound still wasn't working. Restarted, still didn't work. So I looked up on how to fix the sound and stuff, and I think I just screwed up my computer even more. This is my sound settings: enter image description here

none of my output devices from before are showing! enter image description here

this is what my pulseaudio volume control is.

Also the sound button isn't in the top of my computer anymore enter image description here

Can someone help me please? I have been struggling on this for a long time and it is driving me crazy!

EDIT: I got this to come in my sound: enter image description here

But clicking test sound doesn't do anything and the sound stil doesn't work.

The first screenshot shows no sound card. It looks like you connect to an external monitor, could be the headphone and you did not exit the device properly. Redo what you did and make sure you select the PC sound card (Output Device) before exiting the external device.

Could be a dead sound card also or corrupt driver.

What do you read there:

inxi --extra -A

See the given solution there by Mr.reaysawa

You can list the sound cards in the command line:

~$ pacmd list-cards

This should list the audio cards are installed on your pc and detected.

If you give the following message:

>>> 0 card(s) available.

Please try using the following command to detect which audio cards your PC has installed, but not detected.

~$ lspci | grep -i audio

Please tell us the results you obtained to continue to help you.
