I was trying to stop the popping sounds my system was creating every few seconds and now I've got no audio devices. It seemed like a powersave option but I was unable to turn the powersave off. I then found some guides about pulseaudio causing problems and how it might stop the popping if removed. I must have went too far. Any ideas for getting my audio back?

What follows is some system settings that might be helpful.

No devices in the sound settings GUI, which you can see here: http://s8.postimg.org/3zzcoyo85/Sound_Settings.jpg.

Typing:

aplay -l

Displays:
