The 3.11 kernle hit Ubuntu 13.10 a couple days ago, but it was causing all sorts of weirdness, like my sound devices where disappearing. I updated today and I was just back to no playing. On a hunch I ran alsamixer. All the settings looked fine, but just playing around I turned off "Auto-Mute Mod" and now sound is working just fine.
