Comment 7 for bug 1248211

Yes, I'm experiencing the same thing. Also pulseaudio is reporting only Dummy Output, which I assume is connected.
None of the googleable solutions to the pulseaudio problem fix it. I understand that I'm supposed to see my user ID when I type "getfacl /dev/snd/*"
Instead I get this:
tim@sileo:~$ getfacl /dev/snd/*

Does this help?
