Computer audio stopped working

Asked by Wahab Ahmad on 2021-01-11

Everything was working fine before I rebooted my computer. After rebooting, I could not play any audio off of my computer, my computer did not detect my headphones as in input/output device. When I increase or decrease the volume, the widget the pops up says 'Simultaneous Output' instead of the appropriate output device. Additionally, I have another pair of headphones that has a USB input cable, the audio output seems to work fine on this headphone.

Let me know of any further information required to solve this issue.

I started going through https://help.ubuntu.com/community/SoundTroubleshootingProcedure, it asked me to post a question with the following output in Step 3:
