I see nothing in your information that implies there should be any
change in sound or video handling.  There were no library changes,
perhaps earlier than these?

Can you play pure audio through, say, audacious or xmms?

Is it possible that your sound device has gone bad?  Did you notice
any power spikes recently? 

Do you have a spare sound device you can test with?  

If you install pavucontrol, what does it show for devices available to
pulseaudio?

Is there any chance of overheating of your system?  If you turn it off
and let it sit for a while (to cool), and then restart it, do you have
sound and video?

It sounds to me like a hardware error, rather than software or
configuration.
