This morning Software Updater showed notification of new updates. The kernel was part of the update which then required a reboot. Once I rebooted, my sound was gone and no longer recognized buy the system. I have tried all I know to do: restart ALSA (forcibly), unload alsa and pulseaudio and re-install both, none of these has worked.
I need the sound back on this machine ASAP and like an idiot, I have already purged previous kernels from the system before I completely checked everything.
Here is the results of uname -a:
Linux z600-ubuntu-64-bit 3.13.0-37-generic #64-Ubuntu SMP Mon Sep 22 21:28:38 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
UPDATE:
Ok, sound IS working, just not pulseaudio and the sound notifier (speaker icon). I also noticed that most of my system settings are missing in the control panel. What I have in the control panels is:
Language Support, Security & Privacy, Printers, Landscape Service, and Software and Updates.
That's it. Any ideas?

There is no ~/.pulse/default.pa
Also, I have an Aferglow Wireless Headset. After the MOST recent update, my headset works, but the microphone is no longer recognized or working. It works in Windows/MAC OSX though.
