dmesg on 3.11.6

HDMI audio was working at some point in the past. Some upgrades or changes I
did while on Ubuntu 13.04 caused it to stop working, so I tried to upgrade to
13.10. I also tried upgrading to a newer 3.11 generic kernel (which didn't
help). 

$ uname -a
Linux fserv 3.11.6-031106-generic #201310181453 SMP Fri Oct 18 18:54:15 UTC
2013 x86_64 x86_64 x86_64 GNU/Linux

I have the radeon.audio=1 parameter in my kernel command line, and I've got the
1,3 device in my aplay -l. When I try playing a sound through the speakers,
using mplayer, aplay, or speaker-test, it looks like it's working, but I get no
sound.

The TV's sound works fine with other machines, and used to work with this
machine. I've attached my dmesg, the output of avivotools regs hdmi, some
output from aplay, and my asound.conf.
