The sound suddenly stopped working in my Ubuntu, so I googled and followed this link but it doesn’t work to me.

Output of aplay -l:

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC662 rev1 Analog[ALC662 rev1 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: ALC662 rev1 Digital [ALC662 rev1 Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Output of cat /proc/asound/version:

Advanced Linux Sound Architecture Driver Version k3.13.0-24-generic. 

Output of alsamixer

Screenshot of the Systems Settings window which shows that the Sound icon does not appear under the Hardware heading, and most of the other icons are also missing.

I didn't have your system setting issue however I had the sound issue and I tried everything that was ever recommended online, I was only able to fix my PC sound issue by running the following commands:

killall pulseaudio
rm -r ~/.config/pulse/*
rm -r ~/.pulse*

Some directories may not exist, that is OK.


pulseaudio -k

then reboot

I found this solution here, there are also some other recommended solutions if this doesn't work.
